aagaard Kjersti Marie photo Kjersti Aagaard, MD, PhD
Associate Professor
Department of Obstetrics and Gynecology
Baylor College of Medicine (Houston, TX)

Dr. Aagaard is board certified in Obstetrics and Gynecology and Maternal-Fetal Medicine and a Fellow of the American College of Obstetrician Gynecologists. She specializes in the field of Maternal-Fetal Medicine, and has specialty clinical interests in preterm birth, stillbirth, maternal obesity and cardiac disorders, ultrasound diagnosis and testing for fetal anomalies and genetic disorders, and management of pregnancies complicated by infections.

Dr. Aagaard’s research interests include both basic science investigations and translation into clinical research. She is internationally recognized for her work on maternal obesity and nutrition, genomics, the “microbiome” and prevention of preterm birth. Dr. Aagaard also actively conducts clinical research related to both cause and management of common perinatal fetal conditions (preterm birth, stillbirth and fetal growth abnormalities), alongside research in the implications of parallel maternal conditions and behavior (obesity, smoking, and nutrition).

In addition to the Aagaard labs research on epigenetics, they are leading the way in unraveling secrets about our “microbiome.” Of the 100 trillion cells in our body, 90 trillion are microbial. This includes viruses, bacteria, parasites, and other microbes and are collectively referred to as our “microbiome.” Each of these has their own genomic codes, which regulate not only their metabolism but ours. For example, without bacteria we could not make Vitamin K, or convert most of our B vitamins to useable forms. We have recently demonstrated that the pregnancy microbiome is distinct, and in fact with 98% certainty we can actually tell if someone is pregnant simply by sequencing their vaginal microbiome. With respect to pregnancy, the Aagaard lab is funded to understand the microbiome and pregnancy complications leading to later in life diseases.

Throughout her career and training she has raised three children on her own and remained an active member in the community. She is a recipient of the Houston Women’s Magazine “Maximum Mom” Award which is awarded “to a woman who has been an extraordinary mother to her children and mentor to others in providing strong moral character and serving as a role model.”

Karine Clément, MD, PhD
Professor of Nutrition
ICAN: Institute of Cardiometabolism and Nutrition/INSERM/Universté Pierre et Marie Curie (Paris, France)

Prof Karine Clément is MD, PhD, full professor of Nutrition, Division of Cardiometabolism, Pitié-Salpêtrière hospital and at Pierre et Marie Curie university – Paris6 (UPMC). Her medical and scientific background is in Endocrinology, Metabolism and Nutrition. In early 2000, she performed a post-doctoral fellowship at Stanford University, CA, USA where she acquired competencies in gene profiling approaches applied to complex diseases. Since 2011, she is director of the Center of Excellence ICAN Institute de CardiometAbolism and Nutrition, dedicated to innovative Care, Research and training in the field of Cardiology and metabolic diseases. This institute aims at developing individualized medicine in the field of cardiometabolic diseases (http://www.ican-institute.org). Inside ICAN, INSERM/UPMC KC’s team (NutriOmics: Nutrition and obesity Systemic approaches) is involved in understanding the complex pathophysiology of obesity and related cardiometabolic complications combining different “omic” approaches. Her work led to the identification of monogenic forms of obesity (Leptin receptor and MC4R mutations) and to genetic risk factors in common obesity. Developing broader systemic and tissue cross-talk approaches, her group showed notably the importance of inflammatory and remodeling genes in human adipose tissue and links with immune cell modifications and fibrosis. Deeper insight into mechanisms is now undertaken. The team is exploring the link between environmental changes (such as food intake), systemic changes and functional modifications in the adipose tissue in link with organs at its vicinity or at distant sites (liver, intestine, heart). The gut microbiota is of evidence a key actor of this link.

Recently, pioneering results were obtained by metagenomic approaches showing that loss in gut microbiome diversity in human obesity associates with increased cardiometabolic risks. Gut bacterial diversity can be modulated by dietary changes and the challenge is now to identify commensal bacteria and gut-derived molecules associated with improved cardiometabolic health. KC is author of more than 250 publications in the field of obesity and cardio-metabolic health and received several prizes.

She is a member of several national and international scientific committees in obesity and metabolism and contributed to several European Networks in genetics and functional genomics (FP5-Nugenob, FP6-Diogenes, FP6-Hepadip, FP6-ADAPT, FP7-FLIP). She is a member of H2020 consortium ePOs and coordinates the FP7 METACARDIS (http://www.metacardis.net).

Dr. Elaine Y. Hsiao is an Assistant Professor in the Department of Integrative Biology & Physiology at UCLA, where she leads a laboratory studying fundamental interactions between the microbiome, brain and behavior, and their applications to neurological disorders. Her studies on the relationships between the microbiota, immune system and nervous system led her to discover that the microbiota can regulate behavioral, metabolic and gastrointestinal abnormalities relevant to autism spectrum disorder (ASD). Her work in this area, and on neuroimmune interactions in autism, has led to several honors, including the National Institutes of Health Director’s Early Independence Award, distinction as Forbes’ 30 Under 30 in Science and Healthcare, National Geographic’s Emerging Explorer Award and fellowships from the National Institute of Mental Health and Autism Speaks. Inspired by this interplay between the microbiota and nervous system, the Hsiao laboratory is mining the human microbiota for microbial modulators of host neuroactive molecules, investigating the impact of microbiota-immune system interactions on neurodevelopment and examining the microbiome as an interface between gene-environment interactions in neurological diseases.
