Student Experiences

I have spent eight years at the Department of Agricultural Microbiology, TNAU, Coimbatore, for my Master’s and Doctoral degree programs. During my Master’s research, I was well-trained in advanced microbiological techniques and supported with the MHRD-Junior research fellowship. During my Ph.D., I was encouraged to do a part of my thesis research in the USA funded by the prestigious Fulbright-Nehru Doctoral Research Fellowship. I was also funded by the DST-SERB Travel Scheme to present my Ph.D. work at an International conference in Malaysia. Immediately after graduating with my Ph.D., I was recruited as a Post-Doctoral Research Associate at the Indian Institute of Science, Bangalore. I am forever grateful to the Department of Agricultural Microbiology, TNAU, Coimbatore, for turning me into a fine microbiologist with several international publications and a respectable research career.

I did my Masters in Agricultural Microbiology during 2008-2010. The department has and having leading researchers as Professors. I took up fascinating research on Microbial Oil Production for my research. I could get full research support from my mentors as they are trained in Abroad. Through the experience I could pursue my PhD abroad. And now settle as Assistant Professor at Country 5th ranking university. The training has made me a good researcher in the field of Microbiology and I would use it for the betterment of the Society.

Myself Dr.D.Senthamilselvi, completed my master and doctoral degree in this department of Agricultural Microbiology, TNAU, Coimbatore from 2015 to 2022 in the field of plant-microbe interaction and algal bio-fuel production. During this study period, not only I have gain knowledge in various areas of microbiology and agricultural microbiology, but also learnt recent and advanced molecular microbiological techniques. In addition the department also supported by providing MHRD-Junior research fellowship for my master’s thesis research. As a scholar, I had several opportunities to attend national and international conferences, workshops, seminars and trainings. Received best thesis award for my master’s thesis research. I am highly thankful to my mentors and Professors of my department to reach this dissertation. Now I am working as Senior Research Fellow under DST-SERB in plant-microbe interaction.
