Biography

Dr. Chand received his PhD from the University of Delhi, New Delhi, India while studying the protein chemistry of reproductive hormones and was trained in molecular endocrinology at the Indian Institute of Sciences, Bangalore. The postdoctoral training at the Department of Pathology, UNM Health Science Center, Albuquerque, NM involved identification and characterization of blood coagulation factors and their role the cancer biology. As an Assistant Professor at the Center for Infectious Diseases and Immunology (CIDI), UNM School of Medicine, Dr. Chand worked on systems biology based studies to understand the pathogenesis of opportunistic pulmonary infectious diseases and allergic asthma.

He pursued his interest in the field of Respiratory Biology at the Lovelace Respiratory Research Institute (LRRI), Albuquerque, NM, and investigated the molecular mechanisms involved in the programmed cell death and inflammatory responses using the experimental cell culture and animal models of airway diseases and help translate findings in clinical pathologies. Currently, at the Herbert Wertheim College of Medicine, Dr. Chand is serving as an Associate Professor (tenure-track) in the Department of Immunology and Nano-Medicine and the Center for Personalized Nanomedicine.

Research Interests:

Primary research interest involves understanding the mechanisms of Pulmonary and Systemic Inflammation and Lung Tissue Remodeling in Chronic Airway Diseases like Allergic Asthma and COPD. While mucus production is an innate beneficial response, however due to a dysregulation in the underlying mechanisms including the persistent increase in the goblet cell numbers leads to a progressive and fulminant airway obstruction and mucus plugging. In addition, accumulated mucus provides a nutrient-rich niche for microbial infections and inflammation that impedes the lung functions. In this context, we have recently reported that airway epithelium preserve an ‘innate memory’ to help augment a rapid and “trained response” following the secondary challenges. This trained response due to the genetic, epigenetic, metabolomic and signalome remodeling and its interplay with the environmental and biological irritants are being currently investigated in the laboratory.

Primarily the laboratory research involves:

  • Investigating the mechanisms of Airway Epithelial Remodeling
  • Understanding the role of Long Non-coding RNAs in inflammatory responses
  • Role of HIV infection and inhaled substance abuse
  • Role of Mitochondrial dynamics in airway diseases
  • Personalized Nanomedicine in chronic diseases
