Research & Publications

My research often begins with a question drawn from everyday experience: how can changes in skin be measured more accessibly, what environmental cost is hidden inside a skincare routine, or whether bio-based materials can replace synthetic cosmetic ingredients? I explore these questions through prototyping, surveys, statistical analysis, literature review, and scientific writing.

Wearable Skin Science

Design and Evaluation of a Wearable System Using Paper-Based pH Colorimetry and Skin Conductance for Skincare Monitoring Accepted for publication in the Springer conference proceedings of ICWIHI 2026

Developed from the DermaBand project, this paper investigates whether paper-based pH colorimetry and skin-conductance sensing can be combined in a low-cost, non-invasive wearable to monitor changes in skin condition.

I designed and fabricated the prototype, developed the experimental testing protocol, collected and analyzed sensor data, and authored the paper presenting the system design, methodology, findings, limitations, and potential applications.

  • Multimodal sensing - Chemical and electrical indicators in one system.
  • Experimental design - Prototype development and structured testing.
  • Data analysis - Interpretation of pH and conductance measurements.
  • Research output - Full paper accepted for Springer proceedings.

Estimation of Plastic Use from Personal Skincare Routines Journal submission in progress

Inspired by my own skincare use and interest in ingredient-conscious, environmentally responsible beauty, I examined the plastic and carbon footprint hidden within everyday personal-care routines.

I surveyed more than 80 respondents across India, the United States, and the United Kingdom, physically weighed personal-care packaging, and developed a replicable method for converting product size and repurchase frequency into annual plastic-use and carbon-emission estimates. The data were analyzed using descriptive statistics, independent t-tests, and one-way ANOVA.

  • 1.45 kg - Estimated annual plastic use per person.
  • 4.34 kg CO₂e - Estimated annual packaging-related carbon footprint per person.
  • Highest contributors - Shampoo, body wash, and conditioner.
  • Broader finding - No statistically significant differences by age or gender within the sample.
