Chemical Graph Theory
To study the physicochemical, biological, and pharmaceutical properties of chemical compounds, a lot of laboratory equipment is required. Since these experiments are time-consuming and expensive, an alternative method has been proposed to get rid of these constraints. The proposed method of predicting the required properties is nothing but finding the topological indices and performing QSAR/QSPR analysis. The study of the topological indices helps us understand the physicochemical and biomedical properties of many chemical compounds. This research is mainly focused on predicting the physical, chemical, and biological properties of phytochemicals using topological indices. QSAR (Qualitative Structure-Activity Relationships) and QSPR (Qualitative Structure-Property Relationships) analysis will be carried out to study the physicochemical properties and bioactivity of the chemical structures and molecules using topological indices. This research outcome contributes to the Department of Medicine and Pharmacology. The predicted properties and correlation coefficients might help them in designing new antiviral drugs, composite drugs, and drug delivery systems.
Research Areas
Fractal Geometry, Fractal Interpolation and Approximation, Fractal Applications
Fractal geometry and fractal analysis have a wide range of applications in complex analysis (for example Julia and Fatou sets), dynamical systems, economics, mathematical finance (for example modelling stock prices through fractal times series), mathematical biology, computational biology (for instance Feigenbaum attractor, Lorenz attractor, Henon map), number theory (for example Fibonacci sequence), stochastics and many more scientific and engineering branches. Fractal interpolation is the generalised spline interpolation technique and also the most advanced interpolation technique which attracts researchers for the approximation of rough functions and interpolating certain data generated by a function whose certain derivatives are irregular in nature. The presence of the scaling factors in the structure of a fractal interpolant provides a large flexibility to its shape. Using fractal interpolation, one can produce not only irregular objects but also smooth curves by choosing the appropriate IFS and its parameters (scaling factors and shape parameters) on suitable compact spaces. The research in fractal applications includes Solutions of BVPs, Graph Directed Fractal Interpolation, Fractal Image Compression, Fractals and Biology, Scattered Data Interpolation, etc.
Fluid flow, heat, and mass transfer
Fluid mechanics is the study of fluid behaviour (liquids, gases, blood, and plasmas) at rest and in motion. Fluid mechanics has a wide range of applications in mechanical and chemical engineering, in biological systems, and in astrophysics. The transport of heat and mass are fundamental features of fluid flows. As such, thermal-fluid-mass transfer processes are essential to addressing energy problems of conserving energy, enhancing energy efficiency and the overall energy crises. Research focuses on thermal management and thermal control for industrial applications, from the study of high performance heat transfer surfaces. And also extended to fluid boundary layers, which continues to be useful in understanding the characteristics of fluid flow that are pivotal to reducing energy consumption.
A Commutative Algebraic Approach to Generating Functions
The research explores connections between algebraic tools and number thirty, particularly focusing on generating functions and trigonometric sums. A novel approach using commutative algebra has been introduced to simplify and generalize established results, revealing intriguing parallels between reciprocity laws and partial fraction identities. The exploration extends to degenerative Bernoulli and Euler numbers, Umbral Calculus, and Hypergeometric Functions, supported by efficient algorithms in Computer Algebra systems. Current investigations concentrate on the geometric connections between partial fractions and reciprocity laws, the establishment of an algebraic Mittag-Leffler Theorem, and algebraic generalizations of Ramanujan sums with applications to deletion correction codes.
Microlocal Analysis, Pseudodifferential Operators, and Hyperbolic Operators
We are interested in performing a singularity analysis of hyperbolic operators with singular and oscillatory coefficients in this area. It is well-known that these operators exhibit a loss of regularity. Using microlocal techniques (specifically, space-frequency techniques), we capture this loss of regularity by tracking changes in the underlying symplectic geometry. We are also interested in cases where coefficients degenerate, vanishing at certain points, known as Fuchsian operators. For these problems, we have demonstrated a propagation of singularities.

Privacy Preserving Machine Learning
The world generated 2.5 exabytes of data per day in 2018. With the widespread adoption of IoT, this number is expected to cross a hundredfold by 2025. All these data collected are sent to the cloud for storage and analysis. The data is nevertheless encrypted on its transmission. However, the machine learning models for data analysis is built on the decrypted data at the cloud servers. Thus, the data is exposed to the ML service providers. This poses a serious hindrance due to the strict privacy laws by countries, the rigorous data policies of companies, and growing privacy concerns among users.

Computational Graph Theory
Graph theory is a rich and versatile field of mathematics that explores the properties and applications of graphs, which are structures made up of nodes (or vertices) connected by edges. One intriguing concept within graph theory is graceful labelling, where the vertices of a graph are assigned unique labels such that the absolute differences of the labels at the endpoints of each edge are distinct. Another important area of graph theory is the study of metric dimensions, which involves finding the minimum number of vertices required to uniquely determine all other vertices based on their distances to the selected set. This concept has practical applications in network navigation, robotic path planning, and sensor placement. Additionally, graph theoretical concepts play a crucial role in cryptography and authentication techniques, providing robust methods for securing data, ensuring privacy, and verifying identities through the use of complex graph structures and algorithms. These applications demonstrate the broad utility of graph theory in solving real-world problems across various domains.
