Jonathan M. Irish, Ph.D.
Assistant Professor of Cell & Developmental Biology and Pathology, Microbiology & Immunology

Dr. Jonathan Irish trained in cancer biology, immunology, and computational biology at Stanford with Garry Nolan during his Ph.D. research and Ron Levy during his postdoctoral studies.  His lab at Vanderbilt studies how signaling governs healthy cell functions and human disease outcomes.  The lab's approach focuses on single cell tools capable of targeting signaling networks in cell subsets and dissecting immune interactions of cells within human tissue biopsies obtained before and during therapy.  Dr. Irish is also the co-creator of Cytobank cloud software for single cell data analysis.  Recent advances from his group include bioinformatics tools like marker enrichment modeling (MEM), a tool for machine learning of cell identity, and application of mass cytometry (CyTOF) to reveal new, clinically significant cell subsets in human tissue and tumors.  Current projects in the Irish lab focus on cancer and immunology research.

Peter Sutovsky, PhD, Dr.h.c.
Reproductive Physiology, University of Missouri, Division of Animal Sciences and Departments of Obstetrics, Gynecology and Women’s Health, Division of Animal Sciences, Columbia

Peter Sutovsky is Professor of Animal Science in the College of Agriculture, Food and Natural Resources, University of Missouri, also appointed as Professor of Obstetrics, Gynecology and Women’s Health at the School of Medicine, University of Missouri Health System. Since the early 90’s, Peter has studied mammalian gametogenesis, fertilization, and pre-implantation embryonic development with special emphasis on the gamete and zygotic ubiquitin-proteasome system (UPS). He was the first to describe the role of UPS in the regulation of mitochondrial inheritance and introduced a novel concept of extracellular UPS, which has been validated in reproduction and outside the reproductive biology field. In particular, Peter demonstrated the importance of sperm borne proteasomes for mammalian fertilization and the role of UPS in epididymal sperm quality control, a mechanism relevant to male fertility evaluation in livestock, and the diagnosis and treatment of human male fertility. Peter’s collaborative research on the biogenesis and post-fertilization processing of sperm head perinuclear theca influenced the optimization and safeguarding of assisted reproductive technologies/therapies such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Other notable collaborations include the development of transgenic pig model for the study of 26S proteasome and work on rodent model of human endometriosis. Recently, the Sutovsky laboratory has also been focusing on biomarker-based flow cytometric semen analysis and semen nanopurification aimed at improving conception rates in livestock artificial insemination (AI).

As of January 2017, Peter published 169 peer reviewed articles and monograph chapters, of which 156 were cited 5,200 times in SCOPUS (h index =38), and featured on 50 journal/book/trade publication covers. He edited two books and three journal special issues. Beside other editorial board memberships, Peter served on the Board of reviewing Editors of the Biology of Reproduction, and is currently the Section Editor for Reproductive Biology in Cell & Tissue Research, Associate Editor in Systems Biology in Reproductive Medicine and Series Editor in Advances in Anatomy, Embryology and Cell Biology. He holds 13 US and foreign patents, reflecting his involvement in technology development and commercialization. He has been recognized as the inaugural recipient of the USDA-NRI Discovery Award, Big 12 Rising Star Award, and the Distinguished Researcher Award and Faculty Entrepreneur of The Year Award by The University of Missouri. Reflecting his international efforts, Peter received honorary doctoral degree, Doctor Honoris Causa from The Czech Life Sciences University in Prague, a Honorary Professorship from the Universidad Nacional Mayor de San Marcos in Lima, Peru, the oldest University in all the Americas, and was elected a honorary Visiting Professor, Professorem Hospitem of the Charles University in Prague. His work on fertilization and infertility has been funded by USDA, NIH, NIJ, Missouri Life Sciences Trust Fund and various other public and private entities. He is a frequent plenary speaker in USA and around the world, frequent NIH panel member and a senior editor in several leading journals in his field. The Sutovsky laboratory maintains active collaborations with scientists and industry partners in Argentina, Australia, Brazil, Canada, Chile, Czech Republic, Denmark, France, India, Japan, Peru, Slovakia, South Korea, Spain, United Kingdom and USA.


Dr. Shyamala Maheswaran
Massachusetts General Hospital, Boston, USA

Dr. Shyamala Maheswaran’s research  is focused on defining the molecular mechanisms that drive breast cancer progression and metastasis. Breast cancer, initially confined to the primary site, eventually spreads to distal sites, including lung, liver, bone and brain, by invading into the bloodstream. Upon reaching these distal sites, the tumor cells continue to grow and evolve well after removal of the primary tumor resulting in overt metastasis and disease recurrence, the leading causes of cancer-related deaths. Using cell culture and mouse models and patient derived tissues and circulating tumor cells (CTCs) enriched from breast cancer patients’ blood, Dr. Maheswaran's laboratory characterizes the contribution of oncogenic cues, tumor microenvironment-derived signals, epithelial to mesenchymal transition and tumor heterogeneity to breast cancer progression and therapeutic responses. She collaborates closely across several disciplines including Clinicians and Engineers at MGH and is currently the Scientific Director of the Center for Cancer Risk Assessment at the Massachusetts General Hospital (MGH).

Isolation of organelles by flow cytometry: State of the art

Scientific interests
Having used cytometry during my PhD at University Paris XI, I have decided to specialize my scientific activities around this technology to develop methods and protocols associated to biological research issues. I am now managing the cytometry core facility of Imagerie-gif, with a major context in plant cell biology.

Favorite cytometry applications:
-    DNA content analysis (Genome size, ploidy level, cell cycle, endoreplication).
-    Monitoring of genic activity by expression of fluorescent proteins (GFP, mCherry, etc.).
-    Cell metabolic activities measurement (biosensors): Calcium, pH, membrane potential, Reactive oxygen species, etc.
-    Sorting of cells (animal, plant, yeast, bacteria) and organelles.

The main interest of our research is evolution of sex-determining mechanisms. Particular mode of sex determination is important not only at the individual organismal level (i.e. establishment of the sex during ontogeny), but it can also influence population sex ratio and therefore total evolvability and susceptibility to extinction of the lineage in question. We are predominantly focused on reptiles (Sauropsida) as a model group for our research because in general we can find large variability in sex-determining mechanisms in this group. In some lineages sex is determined by sex chromosomes (XX/XY or ZZ/ZW) and in others by environmental factors (such as temperature). We study evolution of sex determining mechanisms and also evolution of genome organisation across lineages of reptiles and for larger comparison also in other vertebrates using various technics of classical and molecular cytogenetics including fluorescent in situ hybridization, laser microdissection or chromosome sorting on flow cytometer.
