Dr. Amit Alexander is an Associate Professor in the Department of Pharmaceutics, National Institute of Pharmaceutical Education and Research (NIPER), Guwahati, Assam, under the aegis of the Department of Pharmaceuticals (DoP), Ministry of Chemicals and Fertilizers, Government of India (GoI). He has overall academic experience of more than 13 years in Novel drug delivery systems, Pharmacokinetics, Biopharmaceutics, Statistical Design, Drug Targeting approaches, etc. He is an active member of the Royal Society of Chemistry (MRSC), London, United Kingdom (UK), Royal Society of Biology (MRSB), London, United Kingdom (UK), Controlled Release Society-Indian Local Chapter (CRS-IC), Mumbai, Indian Academy of Neuroscience (IAN) and a life fellow of Indian Chemical Society (FICS), Kolkata. His research interest is in pharmaceutical dosage form development, novel drug delivery systems focusing on nanoparticles and stimuli-responsive hydrogels for critical pathophysiological conditions mainly for brain disorders and tumor targeting. Dr. Alexander specifically works on controlled release and targeting of the drug by utilizing novel approaches. He has been conferred with various prestigious awards notably, UGC-JRF 2011, Dr. P. D. Sethi Annual Award-2012, Young Scientist at Chhattisgarh Young Scientists Congress-2013, Young Researcher Award-2020, First Prize in several National and International conferences, and many Foreign Travel Grants from Government agencies like SERB, DST, CSIR, ICMR for presenting his research work. He has been listed in the Top 2% scientists from India in World Ranking for 2 consecutive years (2020 & 2021) by Stanford University, USA. He has served as a referee for a number of SCI-indexed International journals and is also serving as a review editor in Frontier in Biomaterial Journal. He has presented many invited talks and oral presentations at various International and National scientific peer conferences and attended seminars and conferences as keynote speaker/chairperson and evaluator.
