Dev Maulik, MD, PhD, FACOG, FRCOG, is Professor and Chair, Department of Obstetrics and Gynecology; the Senior Associate Dean of Women's Health; Chair, Department of Maternal Fetal Medicine, Children's Mercy Hospital; and Professor of Bioinformatics at UMKC School of Medicine, Kansas City, Missouri. Dr. Maulik received his medical degree from the Calcutta Medical College, and his residency and fellowship trainings in India, UK and USA. He obtained a PhD from the University of London, UK.

Dr. Maulik is a fellow of the American College of Obstetricians and Gynecologists, and the Royal College of Obstetricians and Gynecologists, and has been recognized by various nationaland international organizations, and the City of New York.

Christoph Lees is Professor of Obstetrics as Imperial College London; Honorary Consultant in Obstetrics and Head of Fetal Medicine at the Centre for Fetal Care, Queen Charlotte's and Chelsea Hospital, Imperial College Healthcare NHS Trust; and Visiting Professor KU Leuven (Belgium).

Professor Lees qualified from Guy's Hospital, London in 1990, and went on to obtain subspecialty accreditation in fetal-maternal medicine at King's College Hospital, London. In 2001 he established the fetal medicine unit at Addenbrooke's Hospital, Cambridge.

Professor Lees' research interest is on fetal assessment and in particular the use of Doppler ultrasound to assess the health of the baby, scanning in labour, and non-invasive fetal surgery. He is the Chief Investigator of The Trial of Umbilical and Fetal Flow in Europe (TRUFFLE), a Collaboration of Centres across Europe; co-founder of the International Working Group of Maternal Haemodynamics; Board member of the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG), chairman of the ISUOG Doppler and vascular imaging group and member of the ISUOG Safety Committee

Professor Lees was awarded £2.2m grant from the Medical Research Council for first in human studies of high-intensity focused ultrasound in 2017, and a £2.5m grant from the NIHR in 2019 to undertake the TRUFFLE 2 RCT. In 2020 Professor Lees was awarded £253k by the MRC for the PANCOVID project, a Global registry of women affected by COVID-19 during pregnancy. He has published widely in scientific journals and has authored textbooks on fetal growth restriction, maternal haemodynamics and the widely read Dewhurst's Textbook of Obstetrics & Gynaecology.
