Meet The Team

Namrata joined the Pallipurath group as a Research Fellow in 2025. She is developing machine learning models to better predict the co-crystallisation of pharmaceuticals. She received her BA with Honors in Physics from UC Berkeley in 2020, where she worked with the Ginsberg Group as an undergraduate researcher. Her undergraduate thesis investigated the self-assembly of gold nanocrystal superlattices by analysing X-ray photon correlation spectroscopy data.

She then pursued her DPhil in Materials Science as a Rhodes Scholar. Under the supervision of Prof. Rebecca Nicholls and Prof. Robert Weatherup, she used density functional theory to interpret the O K-edge x-ray absorption spectra of layered lithium transition metal oxide battery cathodes. In her spare time, she enjoys reading, cooking and spending time in nature.

Dave is a Research Fellow at the University of Leeds specialising in polarised Raman and X-ray scattering techniques, with an interest in understanding pharmaceutical solid state and solution state structures and interactions. He completed his MChem at the University of Bath in 2021, following a year in industry with the Materials Characterisation Team at Pfizer in Sandwich, Kent and a Masters project with Chick Wilson and Pollyanna Payne, screening co-crystallisations of active pharmaceutical ingredients (APIs) and excipient materials.

He then moved to the University of Leeds in autumn 2021 to study for his EPSRC iCASE PhD in partnership with AstraZeneca, focusing on Angle Resolved Polarised Raman Spectroscopy of single crystals of APIs to model the orientation of functional groups on specific facets, investigate how these deviate from the bulk crystal structure and explore how these impacts physicochemical properties and facet behaviours with the aim to provide insight for pharmaceutical design and process optimisation.

Connor Gibson is a postgraduate researcher investigating the influence of impurities on LiFePO₄ crystal structure and electrochemical performance. He is supervised by Dr David Harbottle, Prof Kevin Roberts and Dr Anuradha R. Pallipurath at the School of Chemical and Process Engineering. His research aims to utilise the iron sulphate co-product from the titanium dioxide industry. It focuses on understanding the impurities within iron sulphate and how they incorporate into LiFePO₄ batteries, by studying crystal structures, organic phase synthesis and data modelling. The goal is to apply this knowledge to support the growing battery industry as the world transitions to electrical power. 

Before pursuing his research, Connor worked in healthcare nursing for several years. Outside the lab, he enjoys cooking, gaming, and adventure.

Gayathri is a second-year postgraduate researcher in the group, jointly funded by the University of Leeds and Diamond Light Source, the UK’s national synchrotron. Her research focuses on understanding the formation of squaric acid-based multicomponent organic materials using a combination of X-ray pair distribution function analysis (I15-1 beamline), high-resolution powder X-ray diffraction (I11 beamline) and Raman spectroscopy. By developing correlative in situ crystallisation methods, she aims to uncover how molecular conformations and structural dynamics evolve during the nucleation and growth of organic cocrystal systems.

She received her Integrated Master’s degree in Chemical Sciences with First Division and Distinction from the University of Hyderabad, India, completing her Master’s thesis under Prof Ashwini Nangia on the synthesis and characterisation of pharmaceutical cocrystals. Outside of work, she can often be found experimenting with new recipes, photographing people and collecting quirky finds.

I am a first year postgraduate researcher working on particle property prediction models at the University of Leeds particularly looking at small organic molecules and how different crystallisation methods affect particle properties, this project is funded by the Henry Royce Institute on the Materials 4.0 CDT and works in collaboration with the CCDC. More generally I'm interested in ways that machine learning and computational modelling can be used to accelerate the drug discovery process.

I graduated from the University of Bath in 2024 with an MChem with drug discovery, completing a study year abroad in my third year at Stellenbosch University. Outside of the office you will usually find me at a basketball court.

Catherine joined the group in October 2025. They completed their BSc in Chemistry at the University of Lincoln where they investigated the controlled crystallisations of three boronic acids using automated pipetting systems, resulting in the characterisation of a previously unregistered polymorph, supervised by Dr Gareth O. Lloyd. This was followed by an MA in English Literature, where they researched relationships between male-presenting characters in three of Shakespeare’s plays, with a foundation of queer theory and presentism, supervised by Dr Christopher Marlow.

Their PhD project aims to improve the predictability of cocrystallisations through machine learning studies of intermolecular interactions, with pharmaceutical applications. This project is EPSRC funded.

Meenakshi is a first-year PhD student working on the project ‘Surfactant Adsorption in Dynamic Environments: Application in Agrochemical Formulation.’ This project aims to investigate the adsorption of surfactants onto active ingredients (AI) in agrochemical formulations, which play a crucial role in crop protection and soil enhancement. By employing advanced techniques such as quartz crystal microbalance, atomic force microscopy and synchrotron-based scattering methods, the study will examine how surfactants interact with AI particles during crystallisation. The findings will help optimise surfactant use to enhance formulation stability, minimise the need for excess additives and improve overall product performance.
