Projects

"If you're not prepared to be wrong, you' ll never come up anything ORIGINAL" 

-Ken Robinson

In 2016, I got a Department of Science and Technology, India SERB Project titled “Theoretical and Computational: Approaches to Adaptation and Plasticity.” I didn’t avail the project because I didn’t have a regular position  at that time . I was not able to find any academic institutes for endorsement to implement the project. 

However during the last 5-6 years, I met many students who show their interests to pursue research work with me.  We began to work together in our free time and learn various exciting frontiers of science together. To a beginner, there are always limitless options and possibilities.  Moreover, once we accept our limitations and that no one knows the future, possibilities also proliferate. 

A relaxed and calm mind always help us in our ‘higher pursuits’ while navigating through chaos and uncertainties.

Some of the following questions keep us engaged to work and carry on with my scientific life!

How synchronization arises in coupled dynamical systems? 

Coupled neurons, chemical reactions, or genetic oscillators at cellular level offer instances of systems that are individually stochastic, nevertheless they exhibit synchronous behaviors. It is not completely understood how synchronous dynamics between spatially separated systems are maintained and sustained. How the forms of coupling and how the time delay in the interaction pathways affect the properties of synchronization?  What is the relationship between the intrinsic time-scale of the system and the time scale of delay in the coupling to achieved stable synchronization? How environmental coupling affect synchronization? We aim to understand the mechanisms of stochastic synchronization and other emergent behaviors in biological systems.

How nonlinear systems evolve in a dynamic environment? 

Adaptation is one of the most important biological processes, where systems evolve by rearranging to survive in the environment confronting them. The enigma in the operation of these complex biological systems is not only the mechanism of generation of oscillations and synchronization, rather understanding the surprising balance of stability and the plasticity that allows the system to become flexible enough, to adapt and have coordinated productive output. 

Weekend Meeting:  

A life ‘most suitable to scientists, explorers, artists, musicians or any person’ is a mixed kind in which curiosity, experimentation, playfulness is blended with fun and relaxation. Therefore, we seek the company of our friends living and working at different exciting areas to have an online interaction to figure out what interesting things they do.

“Whatever your work, to perform well, you should have some good things to eat, and warm and close friendships.”

"To remain in good health and spirits, it is necessary not only to study and work, but to also exercise, relax and to seek the company of friends."

-David Hume, Philosopher's Philosopher

During the difficult times of pandemic in the year 2020, technology helps us connect and it gave us an opportunity to bring people closer to us.

Our Weekend Crew consists of:

1. Amit Jangid, Ph.D Student, School of Computational and Integrative Sciences, Jawaharlal Nehru University

2. Maitri Kshetrimayum, Ph.D Student, Department of Aerospace Engineering, IIT Bombay

"I am currently working on experimental measurement of skin-friction at hypersonic speeds. My work envelopes the development of skin-friction transducer, assessment of its performance in different flow environments inside a shock tunnel, and validation of its measurements. I am keenly interested in the experimental techniques of sensor development and flow visualisation techniques (Schlieren, Shadowgraphy, etc.). In the coming years, I plan to work on modelling and computation of hypersonic turbulence flow, and also work on device development from the aspect of biological applications." - Maitri

3. Vishal Juneja, M.Sc. Physics student, Delhi Technical University

"As per my current experience, I like to study and modeling for coupled nonlinear systems and   experimental designing of mechanical and electronic coupled systems. In the coming years, I would like to work on designing of various ways of detection and analysis on networks of mechanical and electronic circuits of nonlinear systems." -Vishal

4. Isha Sharma, B.Sc (Hons) Physics, Department of Physics, Shivaji College, University of Delhi

"I began my research work studying nonlinear oscillators such as the Rossler oscillator and Circadian oscillator, simulating them both deterministically and stochastically to draw a comparison between the two approaches. My current research work's focal point is the study and simulation of Kuramoto oscillators. The Kuramoto oscillator is an ensemble of several coupled phase oscillators. I simulated the system for different total numbers of coupled oscillators, different topologies of the network (such as star, bipartite, global) and different intrinsic frequency distributions (such as Poisson, bimodal Gaussian, normal distribution) and studied the variation of the order parameter with varying coupling strength for a given configuration of the system."- Isha

5. Anmol Singh, B.Sc (Hons) Physics, Department of Physics, Shivaji College, University of Delhi

"I am currently working on the synchronization of coupled oscillators like the Janus Oscillators, which consist of two phase oscillators having an internal coupling as well as external coupling. The internal coupling produces a variety of interesting observations. Previously I have analyzed and simulated chemical systems stochastically using Gillespie's algorithm like the Lorenz system. Our work focuses on various areas of chaos and non-linear dynamics." - Anmol

6. Ashish Rohilla, B.Sc (Hons) Physics 3rd Year, Department of Physics, Shivaji College, University of Delhi

"I have just started working on time series analysis. This technique is used in order to understand the underlying structure and function that produce observational data of complex systems. Understanding the mechanisms of a time series allows a model to be developed that explains the data so that prediction, monitoring, or control of complex systems can be done." - Ashish
