The group leader:

Dr. Vivek Pachauri studied Chemistry and Biological Sciences (2000-2005) in Dr. Bhim Rao Ambedkar University Agra, in India. In 2005, he received a student research fellowship from the prestigious Jawaharlal Nehru Center for Advanced Scientific Research (JNCASR), Bangalore, in the field of Chemistry. He began his formal research career at the Govt. of India, Department of Science and Technology Unit on Nanoscience and Nanotechnology (UNANST-DST) situated in the Indian Institute of Technology Madras (IIT Madras). In 2006, he joined the Department of Chemistry, Indian Institute of Technology Delhi (IIT Delhi), on a research fellowship and worked on sol-gel chemistry routes for synthesis of chalcogens. Thereafter, in 2007, he moved to Germany for his doctoral work and joined the Department of Nanoscale Science at the Max Planck Institute for Solid State Research (MPI-FKF) Stuttgart under the guidance of Prof. Klaus Kern.

Starting his research career with a focus on chemical routes for self-assembly of nanomaterials, Dr. Pachauri has continued on the integration of chemistry-based approaches for large-scale system-integration and development of bioanalytical platforms. His doctoral work produced a new class of one-dimensional (1D), ion-sensitive field-effect transistors (ISFETs) based on semiconductor nanowires, fabricated site-selectively on a chip using solution-based self-assembly growth. In 2011, Vivek Pachauri received his doctoral degree in Physics from the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. For one year, Dr. Pachauri continued his research at the MPI-FKF as a postdoctoral scientist working on new nanoscale device concepts for applications such as liquid-sensing and optical sensing based on 1D and two-dimensional (2D) semiconductors.

In 2012, Dr. Pachauri joined the Biomedical Signalling Group at the University of Applied Sciences Kaiserslautern under guidance of Prof. Sven Ingebrandt and started activities towards bottom-up system-integration of graphene-based materials as well as silicon-based nanofabrication of ISFETs for biosensor applications. In the beginning of 2018, Dr. Pachauri started his research activities at IWE 1 leading a junior research group focusing on Nanomaterials and Bio-Nano Interfaces.

Main interests of the research group are new materials integration, evolution of Bio-Nano Interfaces for advanced sensors and the role of such integrated materials and interfaces in post-CMOS technologies. Dr. Pachauri has published more than 25 peer-reviewed articles in international journals.
