Prof. David Elad, DSc

  • Speaker Type: Infant Suck Lecture Pack 2015
  • Country: Israel
Biography:

David Elad is a Professor of Biomedical Engineering at Tel Aviv University since 1985.  He received his B.Sc. in Mechanical Engineering on 1973, M.Sc. and D.Sc. in Biomedical Engineering on 1978 and 1982, all from the Technion, Haifa, Israel. He was then awarded the Rothschild and Bantrell post-doctoral fellowships at Imperial College London and M.I.T.    
David pioneered computational studies of biofluid transport phenomena in the nasal cavity in the late 80's. In the early 90's he established a comprehensive research program in bioengineering of human reproduction, both at Tel Aviv University. He developed his expertise in the fields of Respiratory Biomechanics and Reproductive Bioengineering, from complete organs all the way to the cellular levels. The respiratory studies included integrative assessment of respiratory muscles, transport phenomena in the human nose, objective noninvasive evaluation of nasal function and mechano-transduction of nasal epithelial cells cultured under air-liquid interface conditions, including effects of air-pollution. The reproductive studies included the role of uterine peristalsis in early human life, pre-implantation embryo transport after IVF, feto-maternal blood circulations in the placenta, transport of nutrition, pharmaceuticals and carcinogenic materials across a tissue engineered placental barrier, mechano-transduction of cultured ovarian cancer cells and biomechanics of infant breastfeeding. He published over 120 articles in peer-review journals and was the leading editor of 5 special journal issues in reproductive bioengineering, respiratory biomechanics and biofluid mechanics.
David has been a visiting scholar at Imperial College London, Massachusetts Institute of Technology, Northwestern University, Nagoya Institute of Technology, Drexel University, Georgia Institute of Technology, University of Toronto, City College New York and Columbia University. He is a member of the World Council for Biomechanics (2002-14) and a fellow of the American Institute for Medical and Biological Engineering (2004), the Biomedical Engineering Society, USA (2005) and the International Academy of Medical and Biological Engineering (2013).
Dr. Elad is currently on sabbatical leave from Tel Aviv University and affiliated with the Department of Biomedical Engineering of Columbia University.

Biomechanics of milk extraction during breast-feeding
The physical mechanisms executed by the infant during breastfeeding have been intriguing topics that lead to a long scientific controversy; whether it is sucking of the milk or mouthing of the nipple/areola. We developed a dynamic analysis of ultrasound video clips acquired during breastfeeding in order to explore the kinematics of the tongue. Then, we have developed a three-dimensional biophysical model of the breast and lactiferous tubes that enabled mimicking latch-on and the dynamic characteristics of the tongue and nipple observed in ultrasound imaging during breastfeeding. Then, we simulated breastfeeding and explored the biomechanical aspects of breastfeeding. We demonstrated that latch-on to draw the nipple/areola into the infant mouth, as well as milk extraction during breastfeeding, require development of time varying sub-atmospheric pressures within the infant's oral cavity. Analysis of infant tongue motility was compared between breast and bottle feeding. The presentation will also include discussion of oral pressure measurements.
