Healthspan Lab

At the HSG Healthspan Lab, we explore the intersection of health, human performance, entrepreneurship, and longevity.

Our research examines how physiological health influences the people behind organizations and economic decisions, from entrepreneurs and executives to investors and other decision-makers. We investigate factors such as sleep, stress, metabolic health, and other physiological processes to better understand their role in performance, judgment, decision-making, and well-being.

A further focus lies at the intersection of longevity, innovation, and entrepreneurship. Advances in prevention, biomarkers, health technologies, and data-driven approaches are creating new opportunities for entrepreneurs, investors, and society. We study these developments from both scientific and entrepreneurial perspectives.

Our ambition extends beyond generating scientific knowledge. We aim to translate research into real-world impact by connecting scientific insights with new concepts, entrepreneurial solutions, and knowledge transfer. Through our research, publications, podcast, and collaborations, we bring together researchers, entrepreneurs, investors, and practitioners to contribute to healthier, longer, and more productive lives.

Developed by Prof. Dr. Dietmar Grichnik and Prof. Dr. med. Aju Pazhenkottil, the Healthy Aging Navigator brings together entrepreneurial and medical perspectives to translate scientific evidence and clinical expertise into a practical framework for healthy longevity. Integrating cardiovascular health, resilience, sleep, nutrition, physical activity, stress management, and social resources, the project takes a holistic approach to understanding the factors that support long-term health and sustainable performance. Particular attention is given to leaders and high performers, whose demanding professional environments can place distinct pressures on health and well-being. By connecting medical expertise with research on entrepreneurship and human performance, the Healthy Aging Navigator aims to make evidence-based insights actionable in both professional and everyday life.

About the Study

This study examines how stress affects key characteristics of the entrepreneurial mindset and whether neurochemical processes can buffer these effects. In a double-blind, placebo-controlled experiment with 119 participants, the study shows that stress can reduce optimism and risk propensity, while enhanced dopaminergic and noradrenergic activity can buffer these negative effects. The findings further suggest that this buffering effect is stronger among individuals with higher entrepreneurial intentions.

Journal of Management, 51(7), 3148–3180

About the Study

This study examines how women entrepreneurs’ physical attractiveness influences male investors’ evaluations. In an experiment with 106 experienced investors, attractiveness was associated with higher perceived competence and increased cortisol responses, which in turn shaped investors’ screening evaluations. The findings highlight how both cognitive and physiological mechanisms can contribute to bias in early-stage investment decisions.

HSG Impact Award 2026

The Innosuisse innovation project “AI-based nutritional assessment of malnourished patients in care facilities” was named one of three winners of the HSG Impact Award 2026.

Developed at the HSG Healthspan Lab by Prof. Dr. Dietmar Grichnik and Dr. Robert Schreiber, the project led to ALPINA+SANA and an AI-powered system that detects and assesses patients’ food intake in real time. With an accuracy of around 90%, including for complex meals, the technology supports the early detection of malnutrition while reducing the need for manual documentation. Initial implementation at Kantonsspital Winterthur demonstrates the project’s practical impact, including reduced documentation effort and treatment costs as well as improved patient care. More than 50 hospitals are already exploring adoption.

The HSG Impact Award recognizes research at the University of St.Gallen that creates tangible impact for society and translates scientific knowledge into practice.

2026 W.A. de Vigier Award

The W.A. de Vigier Award is Switzerland’s oldest award for young entrepreneurs and one of the country’s most highly endowed startup prizes. Each year, the foundation recognizes promising young ventures based on the entrepreneurial profile of their founders, innovation, societal relevance, technical and financial feasibility, market potential, and competitiveness. In 2026, five winners were selected from more than 200 applicants, with each receiving CHF 120,000 in non-dilutive funding. ALPINA+SANA, led by CEO and co-founder Dr. Robert Schreiber from the HSG Healthspan Lab, was named one of the five 2026 winners.

The company addresses malnutrition in healthcare by combining early detection with targeted nutritional intervention. Its AI-powered monitoring system analyzes patients’ food intake from meal trays, helping healthcare providers identify patients at risk of malnutrition earlier. Patients can then receive specially developed medical nutrition products designed to support adequate and sustained nutritional intake. By integrating digital monitoring and nutritional treatment, ALPINA+SANA aims to improve patient care while reducing manual documentation and the healthcare burden associated with malnutrition. Its combination of technological innovation, a significant unmet healthcare need, and the potential for real-world impact contributed to its recognition with the 2026 W.A. de Vigier Award.
