Assistant Professor Navin Kumar Verma is an Assistant Professor of Immunology and Cell Biology at the Lee Kong Chian School of Medicine, Nanyang Technological University. He obtained PhD in Clinical Medicine from Trinity College Dublin (TCD), Ireland’s most prestigious University, under the supervision of Professor Yuri Volkov and Professor Dermot Kelleher. He then undertook postdoctoral research training at the Institute of Molecular Medicine, TCD, where he studied the integrin LFA-1-mediated signaling pathways involved in T-cell cytoskeletal remodeling and migration. He was trained in various aspects of Immunology, Cell Biology, Hematolymphoid Malignancies and Nanomedicine.
Asst Prof Verma has made significant contribution in the area of lymphocyte signaling. He has published more than 35 peer-reviewed papers, which are widely cited (h-Index 13) in the field of immunology, cell biology, cell signaling, pharmacology, toxicology and nanomedicine. In a recent ground-breaking discovery, his research team demonstrated a novel gene silencing technique applied to primary human T-lymphocytes using molecularly-targeted GapmeR. He is co-author of 8 patents.
Asst Prof Verma has received several awards and prizes for his scientific achievements. These include the Glory of India Award, SERS Innovative Scientist of the Year Award, best presentation awards at scientific conferences and the first prize for outstanding business plan of his research in the Trinity Heat of Idea to Product (I2P) coordinated by the University of Texas at Austin I2P® Program. He has served as a reviewer for national and international research grants and scientific Journals.
The main research interest of the lab is centered on developing new ways to treat immune-mediated inflammatory disorders (e.g. rheumatoid arthritis, psoriasis), skin diseases (e.g. melasma, atopic dermatitis), superficial infections (e.g. skin/wound infections) and cancer (hematolymphoid malignancies). His research team employs cutting-edge tools and advanced technologies to understand disease mechanisms at subcellular and molecular levels using various in vitro and in vivo model systems.
Research in Asst Prof Verma’s lab is focused on the following major multidisciplinary projects:
- Elucidation of molecular processes mediated via adhesion receptors in lymphocytes; in particular, biological roles and functional significance of the integrin LFA-1 and associated signaling and adaptor proteins in T-cell migration.
- Identification of signaling protein interactome involved in the active locomotion of T-lymphocytes.
- Characterization of inflammatory skin disorders for biomarker discovery.
- Development of novel gene silencing-based therapeutic strategy that could be combined with nanotechnology enabled controlled-release drug delivery systems for targeting skin diseases, hematolymphoid malignancies and other cancer, in addition to immunotherapeutic applications.
- Exploitation of the anti-inflammatory and anti-infective properties of multi-functional bioactive peptides/polymers for treating superficial infections and wound applications.
