Palsamy Periyasamy, PhD

This profile is part of a series to highlight the researchers who will be honored at a ceremony on Feb. 24 for UNMC's 2021 Scientist Laureate, Distinguished Scientist, New Investigator and Community Service to Research Award recipients.

The New Investigator Award

The New Investigator Award is given to outstanding UNMC scientists who, in the past two years, have secured their first funding from the National Institutes of Health, the Department of Defense or other national sources. New Investigator Award recipients also need to demonstrate scholarly activity, such as publishing their research and/or presenting their findings at national conventions.

  • Name: Palsamy Periyasamy, PhD 
  • Title: Assistant professor, UNMC Department of Pharmacology and Experimental Neuroscience
  • Joined UNMC: 2010 
  • Hometown: Ariyalur, Tamilnadu, India 

Research focus:  

  • Epigenetics
  • HIV and substance use disorders
  • Neuroinflammation  

Why is research important in the world today?  

Because scientific research is the means of the development of human societies. Also, research empowers us with knowledge, drives onward progress and increases the quality of life.  

My research will make a difference because: Drug abuse among HIV-infected individuals poses a significant health burden to society. One of the hallmark features of drug abuse is increased glial cells activation in the setting of HIV-1 infection. My research goal is to investigate the molecular and epigenetic mechanisms involved in HIV-1 (viral proteins) and drug abuse-mediated neuroinflammation. Information gleaned from these studies will form the basis for the future development of novel therapeutic approaches to mitigate central nervous system complications of NeuroHIV.

The best advice I’ve ever received is: Hard work pays off if you're patient enough to see it through.

Three things you may not know about me are: 

  • I write Tamil poetry.  
  • I enjoy playing with kids. 
  • I love to chat with friends.

I am extremely happy to see the achievements of Dr. Palsamy. The extent of happiness is no way inferior than his parents proud of their son.. At this juncture, I remember the day when Palsamy wrote the entrance examination for admission to PhD programme. You submitted the answer paper within 30 minutes though the duration was fixed as one hour. Above all you secured 50 marks out of 50. That day itself I judged your knowledge. The knowledge coupled with hard work, patience and kindness has elevated you at this level. I wish you all in your future endeavours. Prof. S Subramanian, University of Madras.

I am very happy to know your achievements. So far I know that Knowledge leads to success and hard work leads to great success . Now I came to undestand that patience is essential for success. I predict you that you will raise up to the occasion when you secured 50 marks out 50 in your PhD entrance examination that too you have submitted the answer script within 30 minites though the duration was fixed as one hour. Above all I like your sense of humor when you move with your research colleagues more specifically Dr. Gowthaman and Dr. Rao who is currently a Professor in a Medical College in Malaysia . Without your true contribution many of your research colleagues could not achieve their goals within the stipulated period. I wish you all success in your future endeavours. With best personal regards. Prof. S.Subramanian.
