Joel Johny

BS–MS Physics student specializing in complex systems, with a strong focus on network science and algorithm development. My research centers on modeling real-world networks including epidemic spread, transportation systems, and opinion dynamics using computational and data-driven approaches. I have experience in algorithm design, scale-free network construction, and large-scale data analysis.

Major Project at Indian Institute of Science Education and Research (2025-01-06 – Present)

Developed a dynamical frontier containment framework for controlling cascade propagation in complex networks under the supervision of Dr. DV Senthilkumar.

• Applied Targeted Iterative Avoidance (TIA) to isolate target nodes and derive a structural decomposition of the network.
• Identified critical boundary nodes using a graph-coloring-based strategy to suppress cascade reinforcement pathways.
• Implemented and tested the framework on Erdős–Rényi, scale-free, and real-world networks (LastFM Asia, Mozambique COVID contact, and collaboration networks).
• Achieved complete target survivability with minimal shielding cost, outperforming separator-based approaches.
• Co-authored (second author) a research manuscript based on this work; currently submitted to Chaos.

Summer Internship at Indian Institute of Science Education and Research (2024-06-01 – 2024-07-15)

Conducted research on aerosol properties under the supervision of Dr. Anand Narayana Sharma.

• Analyzed spectral AOD data and computed Ångström parameters to study aerosol size and variability.
• Conducted time-series analysis using MODIS and ground-based datasets.
• Applied computational techniques for environmental data processing and interpretation.
