Learners enrolled: 1662
This course on Biomolecules is one of the basic course for all PG Students of Biological Sciences. This is 4 credit course. Gives an overview of importance of biomolecules starting from the simplese molecule, water. Elaborate the need to study proteins: Their 3D Structure,protein seperation,sequencing etc. To understand the pathology and identifying biomrakers using clinical proteomics. Explain in detail DNA,RNA their structures, interactions role in disease,genomics.epigenetics. Enumerate the role of carbohydrates,lipids and their cellular function in physiology and pathology. To briefly introduce to system biology

Phil students as Chief- and co-supervisor and trained about 70 students from outside AIIMS She published more than 100 papers in International journals with high Impact Factors; written Reviews and authored two text books, “An Introduction to Biophysics” and “Studies on Carbapenemase and Membrane Proteome of Acinetobacter baumannii”;Chapters in text books of ‘Biochemistry”, NATO-published “Membrane biology” and e-book of NISCAIR-CSIR. She was the PI for developing E-Content for e-PG PATHSHALA under UGC-MHRD Project and National Coordinator for INDO–FRENCH Collaboration: between ICMR – INSERM programme on “TRE associated neuro disorders: “Fragile X, Friedreich’s Ataxia and other mental retardation”. Dr Rajeswari's major research interest has been 'Conformation of DNA, Protein and DNA-Protein Interactions in Health and Human Disease'. Her research interests include –a) the pathophysiology of unusual DNA structures in neurodegenerative disorders, FRDA, SCAs (2,3,12) which are associated with DNA repeat expansions and developing Biomarkers using Proteomics and nucleic acids ; b) Functional role of DNA binding HMG proteins in cancer progression and potential role as tumor markers ;c) application of DNA triple helix forming oligonucleotides as therapeutics in human disease. She received 18 Research grants from by DST, DBT, UGC and ICMR. She is the Organizing Secretary of: International Conference on “Advances in Molecular Mechanisms of Neurological Disorders” 2013;“One day Seminar on Integration of Teaching and Research in Biophysics at Graduate and Postgraduate Level”,2014 and International Conference on “Friedreich’s Ataxia and DNA Structure in Health and Diseases”, 2015 at AIIMS. Currently she is the National CoOrdinator for the UGC-MHRD -PG Pathshala to develop econtent at PG level for the subject Biophysics.
