Ofri Hefetz

I am a PhD student under the supervision of Dr. Kfir Bar. My research focuses on the intersection of mental health, natural language processing (NLP), and audio signal processing. I aim to utilize computational methods to bridge the gap between clinical psychology and objective diagnostics.

  My research projects include:

1. Computational Diagnosis via Vocal Biomarkers: I am developing non-invasive computational tools for the early detection and diagnosis of mental health conditions, for example Postpartum Depression (PPD) and Post-Traumatic Stress Disorder (PTSD) through voice samples.
2. Objective Frameworks for Treatment Evaluation: Current assessments of clinical treatment quality largely depend on subjective self-report questionnaires. My research seeks to establish objective evaluation metrics by analyzing changes in vocal patterns and symptom progression, providing a quantitative measure of treatment efficacy.
