Dr.B.S.Sreeja, received her Bachelor of Engineering degree from Bharathidasan University, Trichy in 2002 and the Master of Engineering and Doctoral degrees from Sathyabama University, Chennai, India. As her credential she was a district topper in her school board examinations.

As a part of her research she has designed and implemented a low-power low-noise MEMS based Voltage Controlled Oscillator for wireless communication applications, especially in 2.4GHz frequency range. The work was supported by Linton University College Malaysia.She has over 14 years of teaching experience including an overseas experience of 3.5 Years. She has received funded project from BRNS and international travel support from DST.

In her teaching experience she has guided more than 70 UG and PG projects. In her credit, she filed few patents and published 40 refereed Journal papers and more than 60 Conference papers. Her current research interests involve Devices including MEMS, NEMS and RF structures.
