I received my Ph.D in Biotechnology in 1994 jointly from Institute of genomics and integrative biology, Delhi and Indian Institute of Technology Roorkee, India. I conducted my postdoctoral research at Nagoya University, Japan and Lund University, Sweden. I worked as guest faculty of Biotechnology in Lund University, Sweden and also worked as a group leader in a Biotechnology company in Sweden. I also worked as a co-coordinator for the Swedish center for Bioseparation in the area of nano/microparticle separations during 2001-2004. I served as visiting professor at Lund University Hospital, Sweden and Miyazaki University, Japan and am currently visiting professor at Aalto University, Finland. I am currently Endowed Chair Professor of Bioengineering at the Department of Biological Sciences and Bioengineering, Indian Institute of Technology Kanpur, India. My current research interests are in the area of biomaterials, tissue engineering, regenerative medicine, stem cell research, bioprocess engineering, bioseparations, nanotechnology and environmental biotechnology. I have published more than 170 peer reviewed research papers in International Journals, have written twenty book chapters and have many patents granted and filed in my area of research. I serve as the editor of five books on cell separations, biomaterials, nanobiotechnology and biomedical and biotechnological applications. I served as associate editor of Nanoscale Research Letters and is on the editorial board of several other Biological and Biotechnological Journals. I am the executive board member of the Asian Federation of Biotechnology. I also serve on expert committees for Biomaterials and Tissue engineering research and teaching in India and also serve as a committee member of Ministry of Science and Technology, Govt. of India. Some of my major research achievements in the regenerative medicine have been designing of functional biomaterials and therapeutic approaches for critical defect healing of bone, liver, diabetic wounds, peripheral nerve and developing bioartificial lever support bioreactor using cryogel matrices which are at the pre-clinical and clinical evaluation stages. In the area of bioseparations and bioprocessing, I have developed the technologies and processes like metal affinity precipitation, ATPS for protein and cell separations, monolithic chromatographic approaches for macromolecules and cell separations and disposable polymeric bioreactors for therapeutic protein production and have transferred technology to HLL Lifecare, India. My other research achievements are in the development of stem cell separation technology and leukocyte filtration devices. In the area of environmental biotechnology, I have suitably designed membrane filtration devices for air and water purification. I am conducting active International research collaborations with Finland, Germany, Sweden, UK, USA, Japan, Slovania and Korea. I worked as the co-coordinator for recently completed Indo-US center for Biomaterials at IITK supported by India-US Science and Technology Forum. With UK, I have recently conducted India-UK, DST-UKIERI award project and India-UK science bridge project. I am presently carrying out clinical research in skeletal tissue regeneration in collaboration with Lund University Orthopaedic department, Sweden. I have been awarded GRO Samsung project award from Korea for health systems research and TATA Innovation Fellowship from DBT, Ministry of Science and Technology, Govt of India for outstanding research contributions. I have around 170 publications, 7263 citations, h-index of 45 and 11 patents granted (8 filled). I have been involved in 29 Research Projects since 2007 (15 in India, 14 internationals) and I have 22 collaborations (11 in India, 11 Internationals). I have mentored 8 Postdoctoral Fellows (4 ongoing) and 25 PhD dissertations since 2010 (10 ongoing), 19 MSc Dissertations since 2007 (1 ongoing) and 5 international students.
