Research Interests: Nonlinear Dynamics, Mathematical Physics, Bio-Informatics, Speaker Verification, Data Visualization, Machine Learning.
Mitaxi Mehta has Ph.D. in Physics from PRL, Ahmedabad. she has worked as a post-doc. fellow at PRL (Ahmedabad), IMSc (Chennai), University of Regensburg (Germany) and IPR (Gandhinagar) . She has been a visiting researcher at ICTP, Trieste in Italy, HRI Allahabad and Central University Hyderabad. Before joining Ahmedabad university, she was an assistant professor at BITS-Pilani Goa. Her research interests are in the fields of classical nonlinear dynamics, chaos and fractals and scale free networks. Recently she has also been working on problems in (1) protein protein networks, (2) speaker verification based on fixed short speech (3) Visualization of health databases and (4) Periodic orbit search algorithms. She is also interested in recreational mathematics and machine learning.
1. Speech Processing:
M.Tech. student Ms. Pooja Patel and I have been interested in identifying feature vectors for speaker verification using short time speech signals with fixed text.
2. Data visualisation:
M.Tech student Ms. Yesha Bhavsar and I have been working with health data of various Indian states. We are interested in analysis of the data and in creating useful visualisation tools based on binary classification based on gender and demography.
3. A Periodic orbt search algorith :
I am working on modification of the monodromy method of periodic orbit search for Hamiltonian systems. A mid-point like method taking energy of the orbit as an independent evolution parameter is being developed. Additionally I have also started to look into the "Hidden Markov Model" as a predictive model.
1. Disease-Disease Protein networks
With M. Tech. students Ms. Priyanka Nimawat, Ms. Seema Aswani and Dr. Manish Datt (School of Applied Science), Disease-Disease network and studied various network properties. The work is yet to be published.
2. Golden ratio and center of mass location
With Dr. Gautam Dutta (DA-IICT), the occurance of golden ratio at the edge of a solid symmetric body with cavity of the same shape was studied. Ref. Euro. J. Phys. 37 (2016) 068002.
