Professor In Young Kim's research lab focuses on the intersection of environmental health and biomedical engineering, with a primary emphasis on understanding the biological impacts of environmental stressors such as ultraviolet radiation and mental stress. The lab investigates molecular mechanisms of skin carcinogenesis and develops advanced physiological signal analysis techniques—particularly using heart rate variability (HRV) and empirical mode decomposition—for early detection of acute stress. Their work aims to bridge clinical applications with innovative signal processing to enable non-invasive, real-time health monitoring and targeted prevention strategies. The lab also explores chemoprevention approaches for skin cancer and stress-related disorders, emphasizing translational research for public health impact.

Exposure to ultraviolet (UV) radiation is associated with approximately 65% of melanoma cases, and 90% of non-melanoma skin cancers (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). While the incidence of most other malignancies has either stabilized or declined, that of NMSC has increased and is developing even in younger age groups. NMSCs account for nearly 15,000 deaths, 3.5 million new cases, and more than 3 billion dollars a year in medical costs in the United
Mental stress is on the rise as one of the major health problems in modern society. It is important to detect and manage mental stress to prevent various diseases caused by stress and to maintain a healthy life. The purpose of this paper is to present new heart rate variability (HRV) features based on empirical mode decomposition and to detect acute mental stress through short-term HRV (5 min) and ultra-short-term HRV (under 5 min) analysis. HRV signals were acquired from 74 young police officer
