Between 2010 and 2015, I had serious health issues due to which I gave up my teaching job. I had around 12 major and minor surgeries during that period. The zeal and love for Biology and love for teaching kept me going. I have informally taught and helped many students during my sick years.

In 2017, I enrolled for Ph.D. Biotechnology at Gulbarga University under a very supportive, encouraging, and learned guide Prof.Ramesh Londonkar. I am presently a research scholar at Gulbarga University.

"Teachers have always played one of the biggest roles in developing us as human beings capable of navigating this world. Rajini ma'am has been the best biology teacher I've had who in fact taught us with so much passion and understanding that it made me choose science going ahead and making a career in the healthcare industry. She goes way beyond just merely preparing us for an exam. She makes us understand the subject, the why and the how and also truly builds value for each of the topic we have thrown at us during puc and entrance exams. I've always had fun learning with her, she is a person who is empathetic, understands a students perspective and very very approachable. She's a teacher who's stayed in my life ever since and I'm so grateful to have had the opportunity to learn from her! "
