The Dept of Physiology was established in the year 2008. The Physiology Dept is involved in imparting training to undergraduate medical students. The Department boasts its state of art facilities including Hematology Lab, Clinical Physiology Lab, Experimental Physiology Lab, Research Lab and well equipped Library with a total of 145 books. In addition to traditional didactic lectures the Dept uses innovative learner centric small group teaching methodologies to impart training in the cognitive, psychomotor as well as affective domain to undergraduate MBBS students. In addition to this, the undergraduate students are also encouraged to participate in research in the form of Short-term Student project under the aegis of the Indian Council of Medical Research and developmental research activities.
Mission Statement; The Department of Physiology focuses on delivering high quality education to MBBS students, by providing them world-class learner centric academic experience using innovative teaching learning methodologies, so as to produce well-trained health care professionals, who are valued members of the medical fraternity. The Department also strives to provide a conducive working environment to its faculty and staff, giving them ample opportunity to develop their professional skills and expertise, and realize their potential as educators and scholars in their respective field.

Academics arow

The Dept of Physiology conducts more than 450 hours of teaching for 1st MBBS students. These teaching hours are distributed among interactive lectures, practicals, tutorials and seminars & symposia as per MCI guidelines. We have organized a guest lecture on “Clues to Healthy Sleep: Sleep on Time” by Dr HN Mallick, Professor, Dept of Physiology, AIIMS was organized by the department at ACMS, Delhi Cantt. Eleven students of 2014-15 batch were awarded distinction marks in the University exam. A team of 2 students of 2014-15 batch reached semifinals of Physiology Quiz competition organized by Lady Harding’s Medical College, New Delhi.

Training arow

Training in Physiology is undertaken through various teaching methods i.e. interactive lectures, group discussions, tutorials, practical classes and quizzes on regular basis.
Open book tests apart from other methods of assessment are also conducted to assess students’ understanding on a given topic.
Quiz competitions & students’ seminars which demand active participation from the students are organized after which verbal and written feedback from students is obtained to give us a true feedback.

  1. Important appointments
    1. Research Pool Officer & Officer-in-Charge (Sep 2008-May 2011), High Altitude Medical Research Centre, Leh (a joint venture of the Army and DRDO)
    2. Physiologist, Institute of Naval Medicine (May 2005-Sep 2008), INHS Asvini, Colaba, Mumbai
    3. Lecturer, Armed Forces Medical College, Pune (May 2011- Aug 2018)
    4. Medical Officer, 403 Field Hospital, C/o 56 APO (Nov 1994-Dec 1996)


  1. Area of Interest: Developed a keen interest in High Altitude Medicine and Physiology, when, immediately after internship in MH Dehradun, he was posted to 403 Field Hospital, located in Ladakh. The two years spent in the harsh yet bewitching clime of this trans-Himalayan land at altitudes from 13,000 to 19,000 feet (including six months at 19,000feet on the Siachen Glacier) laid the foundation for an abiding interest in health and disease at High Altitude and in extreme cold. Subsequently, having completed a MD in Physiology from AFMC, Pune, he got an opportunity to work in the field of High Altitude Physiology and Medicine when, in 2008, he was posted on request to the High Altitude Medical Research Centre of the Indian Army, in Leh, Ladakh. Ever-since, he has been conducting research at HA, even when based in Pune. He completed the last research project for the Army in December 2019, shortly before he took premature retirement in Jan 2020. He is also an ardent and engaging medical teacher having taught MBBS, nursing, dental, para-clinical and MD students over a 16 years long teaching career.
