About my research

    I am a PhD candidate in the Environmental Engineering Program at the School of Chemical, Biological & Environmental Engineering, Oregon State University. I am currently working on "Microbial Adhesion and Transport" and upscaling of the observed phenomenon. I have been at OSU for past 5 years and completed my MS in Summer 2005. My master's thesis is titled Metabolic Uncoupling of Shewanella oneidensis MR-1, under the presence of excess-substrate and 3,3',4',5 Tetrachlorosalisylanilide (TCS). I completed my baccalaurate degree (BE) in Environmental Engineering at the Deptartment of Civil & Environmental Engineering, Delhi College of Engineering (DCE), Delhi, India in 2003.

    Following is a brief summary of my gradute research. I will keep on updating this page in future as my research progresses. So stay tuned...

A Typical day in Lab

Research Interests

    My research interests are evolving and I presently enjoy working in the broad areas of flow and transport phenomena, environmental microbiology and bioremediation. Mathematics is an area I'm currently exploring and like to grapple with differential equations in my free time. I have recently been introduced to the upscaling techniques and am looking forward to incorporating them in my research. Imaging and microscopy are other areas in which I would like to delve. I already have some expertise in Epi-fluorescence microscopy and am looking forward to learning Atomic Force Microscopy.

    My research interests span the following areas:

      Bacterial Adhesion and Transport Theory
      Bacterial Hydrophobicity and Hydrophobic interactions
      Bioremediation
      Microbial Fuel Cells
      Biofilms
      Effect of nanoparticles on Microbial systems

Current Activities

    I visited Ben Stottrup's Lab at Augsburg College, Minnesota to learn the operation of Langmuir-Blodgett Trough and monolayer deposition. I also had the opportunity to present a talk to undergraduate students, mostly biophysics majors about some of my research.
