What are some of the key challenges that you encounter (infrastructural, regulatory, or collaborative) and how do these influence the pace or direction of your work?
I work at the Department of Chemistry at IIT Guwahati in the north-eastern part of the country. Although the region is developing rapidly, it still lacks sufficient research institutes, major chemical warehouses, and offices for instrument suppliers. This makes procuring specialty chemicals a lengthy process, and arranging for service engineers to visit takes time as well. The absence of nearby institutions with advanced equipment limits collaboration. Additionally, funding from research agencies is often reimbursed late in the financial year, creating a resource imbalance. Purchases must be completed quickly, which is especially challenging for large instruments ordered from foreign countries.
India aspires to become a global leader in science and technology. What steps do you think are crucial to strengthening India’s position in international scientific collaborations, especially in emerging domains including, but not limited to, biotechnology, semiconductors, quantum technologies, AI/ML, space technology, and renewable energy?
Enhancing India's standing in international scientific collaboration hinges on strengthening its research capabilities. For Indian science to truly excel, it must capture the interest of foreign partners. The interplay between science and technology and research funding is vital; thus, India should allocate larger budgets to these areas. It's crucial to ensure that research funding reaches a wider array of scientists across the nation. While emerging sectors require significant support, it is equally important to maintain investment in basic sciences, which serve as the cornerstone for the future of the scientific community. There is an urgent need to establish new institutions aimed at attracting talented scientists who are currently based abroad, addressing the challenge of brain drain. Furthermore, increasing the availability of international grants to facilitate seamless mobility for researchers is essential. Promoting closer collaboration between academia and industry, both nationally and internationally, would also represent a significant advancement.
As we celebrate the legacy of C. V. Raman and the Raman Effect, could you share what scientific breakthroughs inspire your work today, and what impact do you hope your research will have on a national or global scale?
I have been trained as a peptide chemist, a field greatly influenced by the ground-breaking work of Dr. Robert Merrifield, the father of modern Solid Phase Peptide Synthesis (SPPS), which revolutionised peptide research. I graduated from MBU at IISc, the very department founded by the esteemed Professor G. N. Ramachandran, whose Ramachandran map has taught the world how to analyse peptide conformations and structures. I have been particularly inspired by Professor P. Balaram, a prominent Indian biochemist known for his extensive work on peptides and peptidomimetics. The discoveries of peptide-based drugs such as Insulin, Oxytocin, Vasopressin, Gramicidin S, Polymyxin, and Leuprolide, first-generation medications used to treat diseases like diabetes, infections, and cancer, have motivated me to pursue my current research in the field of peptide therapeutics.
One of the most pressing challenges we face today is antimicrobial resistance. Existing antimicrobials are becoming inefficient for combating infections caused by superbugs that have developed resistance.We develop economically viable therapeutic alternatives, named CAMPs, that have very slow development/complete absence of antimicrobial resistance, being highly efficient in combating infections and biofilms, noncytotoxic, and protease-stable at the same time. We are hopeful that these molecules have strong potential to be translated into future therapeutics.

Scientific research is inherently demanding, particularly in interdisciplinary fields such as metals in medicine, where discovery spans molecular design to preclinical validation. My work integrates synthetic chemistry of organic ligands, transition metal complexes and nanoaggregates, advanced characterization, in vitro, in cell and in vivo studies - requiring sophisticated instrumentation and animal facilities that depend heavily on strong institutional central infrastructure. Regulatory frameworks, especially ethical approvals for biological studies, often introduce significant timelines that influence project execution and funding cycles. Collaboration is therefore essential; effective partnerships accelerate innovation, whereas inefficiencies can impede progress. Ultimately, infrastructural, regulatory, and collaborative challenges do not hinder science but shape its rigor, direction, and translational impact.
India aspires to become a global leader in science and technology. What steps do you think are crucial to strengthening India’s position in international scientific collaborations, especially in emerging domains including, but not limited to, biotechnology, semiconductors, quantum technologies, AI/ML, space technology, and renewable energy?
India is steadily advancing toward global leadership in science and technology, supported by expanded infrastructure and access to advanced instrumentation. However, sustained competitiveness requires stronger integration between academia, industry, and policy. Innovation-driven biotechnology and pharmaceutical companies must expand R&D capacity to absorb highly trained PhDs and strengthen translational momentum. A critical priority is bridging the post-TRL-3 “valley of death,” where many advances in AI/ML, quantum technologies, semiconductors, renewable energy, and drug discovery stall before commercialization. Dedicated translational funding, regulatory streamlining, public–private partnerships, and strategic international co-development platforms will be essential for globally transformative impact.
As we celebrate the legacy of C. V. Raman and the Raman Effect, could you share what scientific breakthroughs inspire your work today, and what impact do you hope your research will have on a national or global scale?
As we celebrate Dr. C. V. Raman and the Raman Effect, I am reminded that transformative science begins with curiosity. The discovery of Cisplatin inaugurated metals in medicine, demonstrating how metals and inorganic complexes can redefine therapy. Today, medicinal inorganic chemistry is evolving beyond DNA targeting toward redox-active, photoactivatable, and immune-modulating metallodrugs. Our research work at IIT Kanpur develops self-assembled metal-based nanoaggregates with multimodal therapeutic and diagnostic potential. I hope this research advances translational medicinal chemistry in India and contributes globally to innovative metal-based diagnostics and therapeutics addressing pressing health challenges.
