  • Research Fellow in Microfluidics Based Biosensing for Point-of-care Diagnostics
  • Dept of Mechanical Engineering
  • Faculty of Engineering Science

Arnab is a mechanical engineer by background and specializes in applying engineering and physical science principles to solve problems related to sensing and vibration. He completed his bachelor’s degree in mechanical engineering with honours from Indian Institute of Engineering Science and Technology (IIEST), Shibpur in 2012. Subsequently, in 2014, he obtained a Master of Science (MSc) degree in mechanical engineering from University of Alberta in Canada. He received his PhD in the field of acoustic biosensors from Loughborough University (LU) in UK in 2018. He was the recipient of Wolfson School Indian International Excellence Studentship for his doctoral studies at LU. During his PhD, he developed a novel method for determination of resonance frequency and dissipation for acoustic resonators using a fixed frequency drive. The developed method was applied for detection of a wide range of biomolecules with molecular sizes ranging from 200 Da to 190 kDa and having relevance to infectious and non-communicable diseases. The novel technique allowed greater signal-to-noise ratio and time resolution. Following his PhD, Arnab worked as a Postdoctoral Research Associate in Dynamics and Healthcare Engineering laboratories in LU for 11 months. During his postdoctoral tenure, he worked on vibration reduction in automotive powertrains using nonlinear vibration absorbers and liaised with Ford Motor Company at Dunton Technical Centre in UK for proof of concept validation. In parallel, he also developed a microfluidics based non-linear acoustic platform for bacterial sensing. He worked as part of a multi-disciplinary research team and with leading academic collaborators in the field, including Stanford, Cambridge, Leicester and Stockholm University during doctoral and postdoctoral studies. After his short postdoctoral stint in LU, he was self-employed as a Technical Manager for 10 months in a national accredited metrology laboratory in Kolkata, India. Soon after, Arnab served as a Research Manager in the Research & Development (R&D) Section at Indian Institute of Technology Guwahati (IITG), where he managed the technical activities of R&D section and assisted academics in writing and developing research proposals. Arnab joined mechanical engineering department of UCL as a Postdoctoral Research Fellow in September 2021 to work with Profs Manish Tiwari and Stavroula Balabani for developing microfluidics based point-of-care biosensors for detection of acute kidney transplant rejection. He will be primarily detecting urinary chemokines which serve as the biomarkers for acute rejection. Clinical work related to his project will be performed at Royal Free Hospital in London, led by kidney transplant surgeon, Mr. Reza Motallebzadeh and his team.
