The research interest is focused toward developing the industrial relevant and sustainability driven solution using biological molecules. He has been actively involved in production strategies for medicinal plants using lab based and hydroponic techniques exploring the metabolome profile of the plants under different abiotic stress and cultivation conditions. He is working on DBT funded project jointly with Prof. Pammi Gauba (Director R & D; Head (Department of Biotechnology, JIIT Noida) on exploring transcriptional variation during the hydroponic cultivation of medicinal plant. Dr. Mathur had published research work in this domain area in journals of repute along with process patents.

He has also been involved in production of non-dairy probiotic fermented juices, and the research work was funded by Department of Science and Technology, Government of India under International Bilateral Research Scheme (India-Egypt Bilateral Research grant).

The growing industrial demands for developing miniaturized rapid detection methodology, has taken the world with stride. Dr. Mathur jointly with Prof. Gauba worked towards the development of biosensor for detection of toxic compounds in cosmetics. The project on development of biosensor for detection was funded by Department of Biotechnology (DBT), Government of India. Dr. Mathur had filed and published patents in the core area of developing miRNA-based biosensors for preliminary diagnosis of diseases.

Currently Dr. Mathur is working on the core area of biochar production, medicinal plant hydroponics, biosensor technology and biopolymer from organisms.
