Jadzia Jagiellowicz, PhD: Researcher, Author, and International Consultant on High Sensitivity (ICHS)

Profession: Researcher, Author, Expert Advisor, and International Consultant on High Sensitivity (ICHS)
Audience: Highly Sensitive People, therapists, coaches, researchers, educators, and helping professionals
Website: Highly Sensitive Society


Have you ever wished there was someone who could explain high sensitivity using science rather than opinions?

As awareness of the Highly Sensitive Person (HSP) trait has grown, so has the amount of information available online. While that has made the topic more accessible, it has also made it harder to separate evidence-based guidance from personal interpretation.

Dr. Jadzia Jagiellowicz is one of the few professionals whose work is rooted in both scientific research and direct support for Highly Sensitive People. By combining academic research with practical education, Dr. Jagiellowicz helps bridge the gap between the laboratory and everyday life.




About the Practitioner

Dr. Jadzia Jagiellowicz is a researcher, author, speaker, and International Consultant on High Sensitivity (ICHS) specializing in Sensory Processing Sensitivity (SPS). Research interests include the biological, neurological, and psychological foundations of high sensitivity, with a particular focus on emotion processing, emotion regulation, stress, and environmental sensitivity.

A Highly Sensitive Person personally, Dr. Jagiellowicz began researching the trait after seeking to better understand personal experiences and those of former gifted students. Research in the field has continued since 2005, making Dr. Jagiellowicz one of the few professionals who combines evidence-based scientific research with education and consultation for Highly Sensitive People.

Professional contributions include peer-reviewed studies on Sensory Processing Sensitivity, chapters in The Highly Sensitive Brain, collaborations with leading HSP researchers including Dr. Elaine Aron and Dr. Bianca Acevedo, and advisory work supporting the HSP community. Dr. Jagiellowicz was also Dr. Elaine Aron's first doctoral student and continues to contribute to advancing research on high sensitivity.

Areas of Focus

Areas of expertise include:

  • Sensory Processing Sensitivity (SPS)
  • neuroscience and biology of high sensitivity
  • emotion regulation
  • environmental sensitivity
  • stress and resilience
  • evidence-based HSP education
  • health and wellbeing
  • medication sensitivity
  • authenticity and personal growth
  • consultation for Highly Sensitive People

What You Can Learn

Through Dr. Jagiellowicz's research, articles, and educational resources, readers can learn:

  • the science behind the Highly Sensitive Person trait
  • how high sensitivity influences emotions and decision-making
  • why Highly Sensitive People respond differently to stress
  • current research on the brain and Sensory Processing Sensitivity
  • strategies for reducing overwhelm while respecting a sensitive nervous system
  • how authenticity, boundaries, and self-understanding support wellbeing
  • practical applications of scientific findings in everyday life

The emphasis throughout the work is on translating research into information that Highly Sensitive People can apply to daily life.

Who This Practitioner Is Best For

Dr. Jagiellowicz's work is especially valuable for:

  • Highly Sensitive People seeking research-based information
  • newly identified HSPs
  • therapists and mental health professionals
  • coaches and educators
  • psychology students
  • researchers interested in Sensory Processing Sensitivity
  • readers who prefer evidence-based resources over anecdotal advice

Services & Resources Offered

Resources and services include:

  • research-based consultation for Highly Sensitive People
  • educational articles
  • scientific publications
  • speaking engagements
  • workshops and presentations
  • media interviews
  • blog articles on HSP wellbeing
  • evidence-based guidance on sensitivity and stress
  • resources through the Highly Sensitive Society

The website regularly publishes articles on topics such as people-pleasing, medication sensitivity, authenticity, decision fatigue, stress management, and emotional wellbeing from an evidence-informed perspective.

Why This Practitioner Stands Out

Several qualities distinguish Dr. Jagiellowicz's work within the HSP community:

  • One of the few researchers combining scientific research with HSP consultation
  • More than two decades of research on Sensory Processing Sensitivity
  • Former doctoral student of Dr. Elaine Aron
  • Contributor to The Highly Sensitive Brain, one of the field's leading academic references
  • Published research on neuroscience, emotion regulation, stress, and medication sensitivity
  • Strong commitment to evidence-based education and practice
  • Trusted advisor within the international HSP community

Any Limitations

Much of Dr. Jagiellowicz's work is grounded in academic research, so some articles and publications may be more detailed or technical than introductory HSP resources.

Readers looking for structured online courses or large community programs may wish to combine these research-based resources with educational offerings from practitioners such as Julie Bjelland or Alane Freund.

Consultation services focus on education and guidance rather than psychotherapy, as Dr. Jagiellowicz is not a licensed therapist.

  • educational articles
  • research summaries
  • consultation services
  • presentations and talks
  • scientific publications
  • blog posts focused on Highly Sensitive People

Personal Take

One of the greatest strengths of Dr. Jagiellowicz's work is the commitment to evidence-based practice.

In a field where personal opinions can easily overshadow research, the focus remains firmly on what scientific studies tell us about high sensitivity and how those findings can improve everyday life. That combination of rigorous research and practical application makes these resources especially valuable for readers who want a deeper understanding of the HSP trait without losing sight of real-world challenges.

For anyone who enjoys learning the "why" behind high sensitivity, Dr. Jagiellowicz's work is an excellent place to explore.
