Profile

Ashutosh Kumar works as an Associate Professor in the Division of Biological and Life Sciences, School of Arts and Sciences, Ahmedabad University, Gujarat, India. He obtained his Master’s degree in Applied Microbiology from Vellore Institute of Technology, Vellore in 2008 and worked at CSIR-Indian Institute of Toxicology Research, Lucknow for his Doctorate degree and was involved in understanding the fate of nanomaterials on biological systems. His current research areas of interest include nanomedicines for cancer and arthritis therapy, DNA Biochip for pathogen detection, nanobased drug and gene delivery, nanoemulsions for food industries, environmental nanotechnology and nanotoxicology.

His group works at nano-bio interface and have passion for understanding the effects of nanotechnology on the human life and environment at large. His deep understanding of the environment combined with his skills in nanotechnology and his versatile analytical understanding of different animal systems allowed him to make significant seminal contributions to the field of environmental nanotechnology. In past, Professor Kumar’s research work has been focused on development of new methods for nanomaterial safety in India. He has developed a novel method for the detection of uptake of nanoparticles in live cells for several generations. Additionally, he has been involved in studying the potential effect of nanoparticles on human cells, mice and aquatic organisms including zebrafish and Tetrahymena. His understanding of the role of abiotic factors in influencing the nanotechnology outcomes of biotic community is outstanding and by far an exemplar in the field. His study makes a significant contribution to understand the possible negative effects of novel technological solutions and the ways to mitigate them.

He has supervised 27 master’s thesis, 5 doctoral thesis and published close to 60 international research articles, 23 book chapters and 3 edited books. His contribution in the field has led to the publication of multiple articles in high impact factor journals. Some of his contributions have also been extensively discussed in the policy documents such as “Guidance on the safety assessment of nanomaterials in cosmetics, prepared by Scientific Committee on Consumer Safety (SCCS), European union, 2019” and in “United Nations in the Asia-Pacific research and training network in Science, Technology & Innovation (STI) policies for sustainable development”.

The impact of his research and his contributions to the field are also evident from the awards won by Ashutosh at this young age. He has won the “Indian National Science Academy (INSA) Medal for Young Scientist 2014” in the area of Health Sciences. Similarly, he won the National Academy of Sciences India (NASI) - Young Scientist Platinum Jubilee Award (2015) in the field of Bio-medical, Molecular Biology and Biotechnology, DBT Young Investigator Award and vLife Science Best Publication Award.

Research

1. Nanomedicine laboratory - Functionalized Nanoparticles for Targeted Biosensing & Biological Applications 

The Nanomedicine Lab integrates nanotechnology with disease biology and materials science to develop advanced solutions for pressing healthcare challenges. Our lab designs sophisticated lipid-based, polymeric, and inorganic nanoparticle platforms for targeted delivery of RNA therapeutics such as siRNA, miRNA, and aptamers alongside small-molecule drugs. Treating complex diseases effectively requires delivery systems capable of precise localization to pathological sites, maximizing therapeutic efficacy while reducing systemic toxicity. To achieve this, our nanocarriers are engineered with mAbs, peptides, and other ligands that bind with high affinity to biomarkers selectively overexpressed in malignant or inflamed microenvironments. This strategy is based on a detailed understanding of disease pathophysiology, allowing for treatments that target both the visible symptoms and the molecular causes driving the condition. A central focus of our research is modulating immune cells, particularly macrophages, and the inflammatory pathways that drive disease progression.

By engineering stimuli-responsive and disease-specific nanocarriers, the Nanomedicine Lab aims to enhance therapeutic outcomes in diseases resistant to conventional treatments. These nanosystems are designed to sense endogenous biological cues such as pH gradients and release their payloads in a spatially controlled manner. Furthermore, we incorporate near-infrared absorbing nanomaterials, including gold and semiconductor nanostructures, to enable photothermal theranostics. This multimodal approach combines localized hyperthermia-induced cytotoxicity with a targeted drug and RNA delivery, providing a synergistic strategy to overcome multidrug resistance and improve clinical efficacy in challenging cancer models. Our research pipeline integrates in vitro studies using disease-relevant cell lines with advanced zebrafish tumor xenograft models to investigate nanoparticle biodistribution, pharmacokinetics, tumor targeting, and therapeutic efficacy in vivo. The inherent optical transparency and genetic tractability of zebrafish enable real-time, high-resolution visualization of nanoparticle dynamics within tumor microenvironments. Complementary preclinical evaluation in specialised rodent models provides us with comprehensive insights into pharmacodynamics, toxicity profiles, and immunomodulatory effects, thereby substantiating the translational potential of these nanomedicines for clinical application.

Long-term prospects:

Clinical applications of nanomedicines and programmable DNA nanodevices for delivery of therapeutic agents to targeted sites.

2. Hazard Identification and Risk Assessment of New Chemical Entities

The growth rate of the Indian plastics industry is one of the highest in the world, with plastics consumption growing at 16% per annum. The Indian plastics market is comprised of around 25,000 companies and employs 3 million people. The State of Gujarat is the leading plastics processing hub and accounts for the largest number of plastics manufacturers, with over 5,000 plastics firms. Microplastics, either manufactured or formed through ageing and weathering processes are a potential planetary boundary threat, resulting in human exposure via dietary intake and inhalation. Microplastics can be small enough to be engulfed by cells, where they are transported by the lymphatic and blood systems and have the potential to bioaccumulate. The principal aim of this project is to obtain fundamental knowledge about:-

  • Identification of sources, pathways and exposure to microplastic contamination
  • Method Development to quantify and characterize the microplastics
  • Investigating the effect, fate, accumulation and biomagnification potential of microplastics.
  • Development of strategies and approaches to remove the microplastics partially/completely from the water bodies
  • Developing Citizen Science Programs to engage the students in microplastic research and mitigation efforts.
  • Applying Science to Policy

Long-term prospects:

Hazard identification and risk assessment of NCEs to human and environmental health and development of strategies to mitigate them.
