Biography

Dr. Chand received his PhD from the University of Delhi, India and got his postdoctoral training at the Department of Pathology, UNM Health Science Center, Albuquerque, NM. As an Assistant Professor at Center for Infectious Diseases and Immunology (CIDI), UNM School of Medicine, Dr. Chand worked on systems-based biology to study the opportunistic pulmonary infectious diseases and allergic asthma. He pursued his interest in respiratory biology at Lovelace Respiratory Research Institute (LRRI), Albuquerque, NM, and investigated the molecular mechanisms involved in programmed cell death and inflammation using the experimental animal models of airway diseases. Currently, Dr. Chand is serving as an Associate Professor (tenure-track) in the Department of Immunology and the Center for Personalized Nanomedicine at Florida International University.

Research Interest

Dr. Chand’s primary research interest involves understanding the mechanisms of airway inflammation and remodeling in chronic airway diseases by specifically focusing on mucous hypersecretion pathways. The projects employ cellular, molecular, and animal model approaches to investigate the role of inflammatory mediators in airway remodeling. The inhalational exposure to various toxicants and allergens causes airway epithelial cells to engage adaptive and cytoprotective pathways. One such mechanism is epithelial cell extrusion whereby dying or unwanted cells are removed while preserving the barrier integrity. And either infrequent or frequent extrusion could occlude the lung function. In certain susceptible population these pathways are dysregulated leading to aberrant mucous production as observed in patients with allergic asthma, cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD).

Current projects include:

  • Investigating the mechanisms of mucous cell survival/death pathways
  • Role of epithelial cell extrusion in chronic airway diseases
  • Role of HIV-1 infection and substance abuse in chronic diseases
  • Targeting chronic diseases with nanotechnology - Inhalational Nano-delivery
