Michael Soares, PhD

Dr. Soares received his undergraduate training at California State University, Chico where he received a B.A. degree in Psychology in 1976 and was engaged in research with William Kalberer and Michael J. Erpino. In 1981, Dr. Soares completed his Ph.D. degree in Reproductive Biology at the University of Hawaii under the guidance of Joan C. Hoffmann and a supportive mentoring environment, including Vincent J. DeFeo, Walter K. Morishige, and Ryuzo Yanagimachi. Dr. Soares received postdoctoral training at the University of California, Santa Cruz with Frank Talamantes (1981-1983) and at Baylor College of Medicine with Stanley R. Glasser (1983-1984). Dr. Soares was recruited by Gilbert S. Greenwald to the faculty at the University of Kansas Medical Center (KUMC) in 1984. He is currently a University Distinguished Professor with appointments in the Department of Pathology and Laboratory Medicine and Obstetrics and Gynecology and serves as Director of the Institute for Reproductive and Developmental Sciences at KUMC and Director of Perinatal Research at Children’s Mercy Research Institute-Kansas City. Dr. Soares has directly supervised the training of twelve graduate students, forty-seven postdoctoral fellows, and five maternal-fetal medicine fellows, and he has mentored seven junior faculty. Dr. Soares’ research has been continuously supported by the NIH since 1986 and has produced 260 peer-reviewed reports, three edited books, and two monographs.

Dr. Soares’ Laboratory investigates specialized survival strategies used by the embryo as it grows within the uterus. Central to the embryo’s survival is the formation of the placenta. This organ gains access to the maternal blood supply and facilitates the delivery of nutrients to the fetus. Dr. Soares’ Laboratory studies how early stem cells develop into the placenta. They have established innovative in vitro and in vivo model systems for investigating conserved mechanisms regulating trophoblast cell differentiation and placental development. Through their efforts we have learned that the placenta develops in response to cues present in the maternal environment; and obstetrical complications, such as preeclampsia, intrauterine growth restriction, and pre-term birth result when the embryo is not successful in its adaptations to the maternal environment. Dr. Soares’ Laboratory’s seminal research contributions to the reproductive sciences have been recognized by the University of Kansas, the International Federation of Placental Associations, and the Society for the Study of Reproduction (SSR) with prestigious research awards.

Dr. Soares joined the SSR as a graduate student 1980 and attended his first SSR meeting that year at the University of Michigan, Ann Arbor. In subsequent years, Dr. Soares and his research group have been active participants at annual SSR meetings. Dr. Soares served as a member of the Biology of Reproduction Editorial Board (1990-1995) and a member of its Board of Reviewing Editors (2005-2013). He served on the Annual Meeting Program Committee several times (1996-2002; 2005-2006, 2017-2018, 2023-2024), the Publication Committee (2001-2002), the Strategic Planning Subcommittee (2003), and the Nominating Committee (2005-2006, 2010- 2012, chair, 2011-2012). In 2013, Dr. Soares was elected as a Director of the SSR Board (2013-2016). Dr. Soares continues to be a strong advocate of the SSR.

Monika Ward, PhD

Dr. Ward is a Professor at the Institute for Biogenesis Research (IBR), John A. Burns School of Medicine (JABSOM) at the University of Hawaii. She received M.S and Ph.D. degrees from the University of Poznan, Poland. In 1999 she was recruited to join Ryuzo Yanagimachi (Yana) in the IBR as a post-doctoral fellow. She established her independent laboratory in the IBR in 2003 and rose through the ranks obtaining a professor position in 2015.

Dr. Ward has been working in the field of reproductive and developmental biology and genetics of male infertility for over 20 years. Her research focus is on spermatogenesis, male fertility/infertility, and assisted reproduction. In recent years her primary interest has been on the genetic aspects of spermatogenesis, and particularly on the role on Y chromosome encoded genes in spermatogenesis and sperm function. The findings from her laboratory highlighted the roles of mouse Y genes in meiotic progression, post-meiotic chromatin remodeling, and sperm formation. Her group also identified the minimum Y chromosome complement necessary for successful assisted reproduction and has shown that the function of these ‘minimal’ genes can be replaced by genetic manipulation of genes encoded on other chromosomes. Her research program is funded by grants from National Institute of Health and Hawaii Community Foundation.

Dr. Ward is an active member of several international societies, including the Society for the Study of Reproduction (SSR), the American Society of Andrology (ASA) and the Society for Developmental Biology (SDB), and has held committee positions within these societies. She has been a standing member on the NIH CMIR study section, an ad hoc member of other NIH and international agencies grant review panels and served on the Editorial Board of Andrology. She successfully organized or co-organized scientific conferences, including Gordon Research Conference on Germinal Stem Cell Biology (2017 and 2019) and International Symposium on the Biology of Vertebrate Sex Determination (2018, 2021 and 2023). At the University of Hawaii Dr. Ward is a chair of the Developmental and Reproductive Biology graduate program, one of the few graduate programs within the USA that offer MS and PhD degrees in reproductive biology and provide students with theory and hands-on training in this field. She is involved in teaching and training undergraduate and graduate students as well as post-doctoral fellows and Junior Faculty.

The SSR is Dr. Ward’s ‘home society’ and it played a vital role in her career development. She has been an active member of SSR since 2001, is a regular attendee at the annual meetings, and has served multiple times as an abstract reviewer, session chair, and session organizer. She was a member of a local arrangement committee for the SSR 2008 annual meeting and a member of Program Committee (2010-2013). She was on the SSR Board of Directors (2017-2020). At present, she serves as an Associate Editor for Biology of Reproduction journal, a member of SSR Virtual Education Committee, and a Co-Chair of SSR 2024 Program Committee.

2022 Distinguished Fellows

Sudhansu K. Dey, PhD

SK Dey obtained his PhD degree from the University of Calcutta, India, in 1972 in Reproductive Biology.  He obtained postdoctoral training at the Univ of Kansas Medical Center and stayed there for almost 30 years. He then moved to Vanderbilt University and is now at the Cincinnati Children’s. He has served and has been the scientific community at many capacities…. as reviewers on NIH and other grants, served in journal editorial boards and still serves as an advisory board member of Journals. SK Dey has been awarded numerous national and international awards and accolades. His group has published more than 350 articles in impactful journals.

SK Dey’s lab is dedicated to exploring the molecular landscape of preimplantation and implantation biology to address emerging and future challenges in the field. Rapid population growth and infertility are two significant global issues that concern the health of children and women. These issues are profoundly influenced by the events of preimplantation embryo development and implantation. Embryo implantation involves an intricate discourse between the embryo and uterus and serves as a gateway to further embryonic development. Synchronizing embryonic development to the blastocyst stage with uterine differentiation to the receptive state is crucial to successful implantation and positive pregnancy outcomes. This process is a complex interplay of numerous signaling molecules and hierarchical instructions to coordinate the embryo-uterine dialogue, which investigators are still working to unfold. Dey’s group utilized genetically engineered mouse models to explore the role of the cytokine, growth factors, transcription factors, homeobox, and morphogen signaling axis in embryo-uterine interactions during implantation. A better understanding of periimplantation biology could potentially alleviate female infertility and develop novel contraceptives. His lab discovered that cooperative interactions among preimplantation embryos promote their own growth via paracrine interactions by growth factors secreted by them. This study exemplified that embryos cultured in groups in a small volume of medium have superior growth than those cultured singularly. Many human IVF programs have adopted this concept to improve embryo growth.

Dey’s group discovered that uterine cyclooxygenase-2 (COX-2) is critical to ovulation, fertilization and implantation, and COX-2 derived prostaglandins (PG) mediate embryo implantation via PG receptors and peroxisome proliferator activated (PPAR) receptors. These studies have profound impact on female fertility and have raised concerns regarding chronic consumption of NSAIDS or COX-2 inhibitors by women during their reproductive life. They discovered that G-protein coupled cannabinoid receptor CB1 and CB2 and their endogenous ligand anandamide are critical to embryo implantation. This study shows that both amplification and silencing of cannabinoid/endocannabinoid signaling adversely affects various aspects of early pregnancy. These observations led to studies in humans showing that higher endocannabinoid levels cause spontaneous abortion in women. They also showed that aberrant cannabinoid/endocannabinoid signaling impairs oviductal embryo transport, which has clinical relevance to ectopic pregnancy in women.  Later, Dey lab have shown that a short delay in timing of implantation or defective implantation creates an adverse ripple-effect throughout the course of pregnancy, leading to defective feto-placental development and poor pregnancy outcome. This constitutes a new concept that embryo-uterine interaction prior to and during implantation set up the subsequent developmental programming. This is consistent with clinical data showing that implantation beyond the normal window of receptivity leads to pregnancy losses in women. His lab was the first to show that COX-1 and COX-2 are major triggers for reproductive cancers, and that COX-1 is the primary factor in ovarian cancer, which argued against the belief that COX-2 was the main cause. This work was followed by a search for the cause of uterine cancer using mouse models. They found that COX-2 and mTORC1 signaling promote endometrial cancer. Combination therapies targeting these pathways showed success in blocking the progression of cancer in mice and, as these pathways are conserved in humans, leads us to possible therapies for human women.

Joy L. Pate, PhD

Dr. Joy Pate is a Professor and the C. Lee Rumberger and Family Chair in Agricultural Sciences in the Department of Animal Sciences of Penn State University, as well as the Director of the Center for Reproductive Biology and Health. She received her Ph.D. from the University of New Hampshire and was appointed as Assistant Professor at The Ohio State University in 1983, where she was promoted to Professor and served a term as Associate Chair of the Department of Animal Sciences. She joined Penn State University in 2008. Her research focuses on the cellular mechanisms that regulate the lifespan of the corpus luteum (CL). Her work has provided insight into cholesterol utilization for steroidogenesis, the roles of endogenous prostaglandin production in luteal function, and the mechanisms by which exogenous prostaglandin results in the demise of the CL. Current research emphases are to understand functional programming of luteal-resident immune cells to regulate tissue homeostasis, and the role of microRNA in regulation of differentiation and rescue of the corpus luteum during early pregnancy.

Dr. Pate has been very active in The Society for the Study of Reproduction, serving as Program Chair, Director, Secretary, President and on numerous committees, and received the Distinguished Service Award from SSR in 2011and the Trainee Mentor Award in 2020. She co-chaired the Organizing Committee of the Inaugural World Congress on Reproductive Biology held in Hawaii in 2008 and was a member of the Organizing Committee of the International Ruminant Reproduction Symposium. Dr. Pate has been involved in undergraduate and graduate teaching throughout her career, including development of study abroad programs to Australia and the Azores, for which she has survived trips with up to 20 undergraduate students for 6 weeks at a time! She enjoys conveying the excitement and mysteries of science to students. 

Sarah A. Robertson, PhD

Professor Sarah Robertson is Professor of Reproductive Immunology at the Robinson Research Institute and School of Biomedicine, University of Adelaide. She received her PhD from the University of Adelaide in 1993 and then held NHMRC Research Fellowships from 1996-2013, with terms at The University of Alberta, Edmonton and Gothenburg University, Sweden. In 2013 she was appointed Director of the Robinson Research Institute at The University of Adelaide and held that post until 2021 when she was awarded a NHMRC Investigator Fellowship to return to full-time research. 

Her research focus is the immune response to conception and pregnancy, and consequences for reproductive success and offspring health. Her discoveries have formed the basis for a new understanding of the origins of maternal immune tolerance at conception. She has identified specific cytokines and immune cells that regulate embryo implantation and fetal development. Notably, she demonstrated that male seminal fluid acts to induce adaptations in the female immune response that can promote or impair receptivity to implantation and affect placental development and fetal growth. Her work shows that the immune system channels environmental signals from both female and male parents to modulate reproductive investment and shape offspring phenotype. These findings are providing novel insights into early life origins of health and informing clinical practise in reproductive medicine.

Dr. Robertson has published more than 220 peer-reviewed papers and is an inventor on 4 patent families, 2 of which have progressed to commercial products. She has trained more than 35 graduate students and 20 postdoctoral fellows and many of her trainees have established their own successful laboratories in reproductive biology.  She has served on several NHMRC committees and grant review panels, including the NHMRC Embryo Research Licencing Committee (2022- ), and Council and Research Committee of the NHMRC (2003-2006). She was Editor-in-Chief of the Journal of Reproductive Immunology (2009-2013) and has held committee and leaderships positions in the Society for the Study of Reproduction, the International Society for Immunology of Reproduction, the International Union of Immunological Societies, and Society for Reproductive Biology. She is grateful for continuous funding support from the NHMRC and the Australian Research Council over her career. Dr Robertson was elected to Fellowship of the Society for Reproductive Biology in 2011, to the Australian Academy for Health and Medical Sciences in 2014, and to The Australian Academy of Science in 2015.

Barbara C. Vanderhyden, PhD

Barbara Vanderhyden is the inaugural Corinne Boyer Chair in Ovarian Cancer Research, a Distinguished University Professor at the University of Ottawa, and a Senior Scientist in the Cancer Therapeutics Program at the Ottawa Hospital Research Institute. Her history in the SSR is founded on training with two notable SSR members. She earned her Ph.D. in Reproductive Physiology with David Armstrong from the University of Western Ontario, and indulged her fascination for oocyte-granulosa cell interactions during her postdoctoral work with John Eppig at The Jackson Laboratory.

Dr. Vanderhyden’s research has explored oocyte-granulosa cell interactions, the risks and processes associated with tumors arising from ovarian and oviductal epithelial cells, the generation and characterization of mouse models with infertility or ovarian cancer, and the discovery and testing of novel cancer therapeutics. Her achievements include co-development of a method for oocytectomy, and the generation of the first transgenic model of epithelial ovarian cancer, more refined, inducible models, and a model for a rare subtype of ovarian cancer. These have been used to explore the mechanisms of tumor initiation and to test new strategies for cancer prevention and treatment. Her 27-year history of managing an ovarian cancer biobank enabled detailed analysis of the expression and function of various therapeutic targets leading to several clinical trials. Her research is currently funded by the Canadian Institutes of Health Research, the National Science and Engineering Research Council, the Cancer Research Society and Ovarian Cancer Canada.

Dr. Vanderhyden has been President of the SSR (2011-2012), a member of the Board of Directors (2005-2008), and a recipient of the SSR Trainee Mentoring Award (2019). She is an elected Fellow of the Canadian Academy of Health Sciences (2020), received the Governor General’s Caring Canadian Award (2014), was selected as one of Canada’s Most Powerful Women (2007) and was one of the Top 50 Champions of Change by the Canadian Broadcasting Corporation (2010), the last one reflecting her commitment to effective science communication. She currently serves on the Board of Directors for Ovarian Cancer Canada and chairs the OvCAN Governing Council which oversees a national (Canadian) strategic research plan to advance novel treatments for ovarian cancer. Dr. Vanderhyden has received numerous awards for research excellence, promoting science education, and her mentorship activities.
