Biography

Dr. Manivannan Yegambaram is a Research Assistant Professor at Florida International University’s Center for Translational Science and is part of the Department of Environmental Health Sciences at Stempel College. He earned his bachelor’s degree in Zoology from Fergusson College and a master’s degree in Health Sciences from University of Pune in India. Later, he received a Victoria University of Wellington Doctoral Scholarship and completed his Ph.D. degree in Cell and Molecular Biology from Victoria University of Wellington in New Zealand. His Ph.D. research under the mentorship of Prof. Paul Atkinson focused on localizing misfolded glycoproteins in the cells arising from a disorder of glycosylation using the Perkin Elmer Evotec Opera high content screening microscope.

After obtaining his Ph.D. degree, Dr. Yegambaram moved to the United States and held two postdoctoral fellowships. First, he worked with Prof. Rolf Halden at the Arizona State University and established the Proteomics and Mass Spectrometry recharge facility. Dr. Yegambaram focused on the assessment of bioaccumulative and toxic organic environmental pollutants in tissue of Alzheimer's disease patients. Utilizing LC-MS, GC-MS and MALDI-TOF mass spectrometry, he identified organ-specific human body burdens to select environmental pollutants/toxicants suspected to constitute Alzheimer's disease risk factors. Later, he joined the College of Medicine at University of Arizona as a postdoctoral research associate and worked with Prof. Stephen Black to focus on Pulmonary hypertension and acute lung injury. Using MALDI-TOF mass spectrometry he identified post-translational modification signature profiles reflective of Pulmonary hypertension and acute lung injury. In 2021, he joined the Center for Translational Science at Florida International University as a faculty member.
