    I. Deputy Director, Bindley Bioscience Center (BBC), Discovery Park, Purdue University

    Website: http://www.purdue.edu/discoverypark/bioscience/

    The Deputy Director provides scientific leadership and assumes administrative responsibilities to manage the seven core facilities (Imaging, Drug Screening, Translational Pharmacology, Proteomics and Metabolomics, Biophysical Analysis, Flow Cytometry, and Informatics) in the BBC. Responsibilities include:

    (i) Providing scientific leadership to the cores facilities-Collaborations, Networking, Resource management and upgrade (including decisions on new instrumentation to remain state of the art)-In 2012-2013 the cores acquired instrumentation worth $5 million)

    (ii) Chair of the Biosafety Committee-this committee is responsible for the maintenance of biosafety standards, educational modules and biosafety training in addition to the programs offered by the Institutional Biosafety Committee (IBC) and the Radiological and Environmental Management (REM) Department at Purdue University.

    (iii) Chair of Space Committee-A committee that makes recommendations for space (100,000 sq ft facility) assignment-key goal is to enhance collaborations and multidisciplinary research by complementary groups and shared instrumentation

    (iv) Human Resource Management. The BBC is staffed by 14 scientists and 6 support staff. I provide guidance through 1-1 as well as team meetings, hiring and downsizing, promotions, and staff relations.

    (v) Engagement and Networking-I play a leading role in promoting BBC capabilities both campus-wide and state-wide. In my efforts to improve engagement, I am organizing a BBC Industry Forum focused on Biological technology development and its impact to discuss grand challenges and Industry-University relations with an Industry Panel and over 30 Industry guests among faculty. This is the first effort at this scale in Purdue (event date is 09/06/2013).

    II. Co-Leader of the Drug Discovery and Molecular Sensing Core of the Purdue Center

    for Cancer Research (PCCR).

    Website: http://www.cancerresearch.purdue.edu/

    The Executive Committee consists of leaders from the five focus areas [Cell identity and Signaling, Medicinal Chemistry, Drug Discovery and Molecular Sensing, Chemical and Structural Biology, Medicinal Chemistry] of the PCCR, along with the Director (Dr. Tim Ratliff) and the Associate Director (Dr. Andrew Mesacar). Key responsibilities of the Core leaders are:

    1) Participate in funding and in decisions relating to research area thrusts of the PCCR

    2) Promote intra-core collaborations through supplemental discretionary funding

    3) Assist in annual progress reporting as well as in presentations and document preparation for Center renewal ($1 million/year for 5 years)

    III. Graduate Chair of Agricultural and Biological Engineering (ABE), The ABE graduate program in Purdue has been ranked #1 ranked consecutively during the years 2009-2013. The program has ~110 graduate students specializing in the areas of Biological Engineering, Bioprocess and Food Engineering, Ecological Engineering, and Agricultural Engineering. Contributed toward the development of new Biological Engineering & Technology (BET) graduate program, which currently has over 40 graduate students. Instrumental in championing and developing a new interdisciplinary Biological Engineering training group as part of the Purdue Life Sciences Graduate program (PULSE). The Graduate committee is represented by the chair and 4 faculty. Key responsibilities include admissions, recruitment, scholarship allocation, graduate plan of study compliance, student awards, and Graduate seminar.

    Other Key Committee Leadership duties : Play a key administrative service role through my involvement with the Strategic Advisory Committee to the Dean (College of Engineering, Ranked #8 Graduate and #10 in Undergraduate program, US News and World report March 2013), to provide critical evaluation of the blue skies plan and assessment of the strategic direction to improve the ranking of the College of Engineering.

    Invested extensively in Purdue's Discovery Park operations and represented my department and the college both at the Bindley Bioscience Center (BBC) and the Birck Nanotechnology Center (BNC). Through the co-directed Physiological Sensing Facility (housed in BBC), my students and I have generously donated our time to promote biological engineering research and educational efforts to the public through Discovery Park organized tours and symposiums. As a member of the Task Force Committee to the BBC I was fortunate enough to participate in discussions to provide a strategic vision to BBC. Co-lead the Breast Cancer Discovery Group and core member of the International Breast Cancer Prevention Committee. The task of our think tank committee is to provide a global vision on breast cancer prevention. Participated in faculty search committees (both as a member and Chair) across disciplines as well as in the College Promotion and Tenure committee (2009-2012).
