Dr. Dar received his BS from University of Kashmir, Srinagar and MS from Bundelkhand University, Jhansi India. Soon after his MS, he qualified the University Grants Commission common entrance examination (UGC NET/JRF) and received a fellowship for five years to pursue his doctoral studies. Dr. Dar joined Academy of Scientific and Innovative Research at CSIR-Indian Institute of Integrative Medicine, Jammu where his main focus of research was to elucidate the neuroprotective potential of small molecules against glutamate/NMDA induced excitotoxicity using different in vitro and in vivo model systems. Soon after his Ph.D., he joined University of Manitoba, Canada as Postdoctoral Fellow where his main focus was to decipher the role of secreted amyloid precursor protein alpha (sAPPα) in neurogenesis and investigate if sAPPα induced neurogenesis could help in ameliorating the cognitive deficits in Alzheimer’s disease. Dr. Dar joined UT Health in 2019 and started working on the role of GPx4 in Alzheimer’s disease with major focus to determine the effect of membrane lipid peroxidation induced by Gpx4 deficiency during Alzheimer’s disease pathogenesis

Dr. Dar’s research is currently focused on elucidating the role of Gpx4, membrane lipid peroxidation and subsequent ferroptosis in Alzheimer’s disease. Ferroptosis is an iron-dependent oxidative form of cell death where a high level of phospholipid hydroperoxides produced in membranes causes cell injury and ultimate cell demise. Gpx4 is the master regulator of ferroptosis due to its ability to directly reduce membrane phospholipid hydroperoxides. Reports have revealed increased levels of lipid peroxidation in Alzheimer brains; however, the underlying mechanism of lipid peroxidation and ferroptosis in Alzheimer’s disease remains unclear. Dr. Dar, under the supervision of Dr. Qitao Ran, is trying to decipher the basic biology and regulation of Gpx4 under physiological and ferroptotic conditions and determine the importance of ferroptosis in Alzheimer’s disease. A variety of in vitro and in vivo techniques are being used in Dr. Dar’s investigation
