Virtual Reality or Real Connection? The Dilemma of the Digital Age | Chrysoula Lazou | TEDxDUTH
In the digital age, we are more connected than ever, yet we often feel more isolated. She explores the paradox of technological connectivity and human disconnection, focusing on virtual reality, digital tools, and their impact on our perception of relationships. With a balanced perspective, she examines both the opportunities and challenges these technologies bring, emphasizing the importance of critical thinking and mindful use of technology to enhance—not replace—our real human connections. Chrysoula (Chryssa) Lazou holds degrees in English, Distance Education, and Immersive Technologies. A researcher at AETMA Lab, D.U.Th., she is pursuing a PhD on technology-enhanced learning for digital and media literacy. Her work explores AR/VR/xR and AI in education. She is an IVLP alumna, Vice President of the International Association for Blended Learning, and Co-Chair of the VR/AR Association – Universities & Colleges Committee. She has led media literacy projects in Southeastern Europe and has received multiple awards, including the UNESCO Global MIL Alliance Award (2nd Prize, 2022) and the Governor General’s Gold Academic Award (2019/2020).

- 13:54Innovation for Precision Vaccines | Ofer Levy | TEDxBostonVaccines are the most effective biomedical innovation saving countless lives yet face growing skepticism. Novel technologies, including systems biology, adjuvants that boost vaccine responses, and cell culture systems that model individual vaccine responses outside the body, promise to make vaccines even better, enhancing safety and efficacy in vulnerable populations. Dr. Ofer Levy was born to and raised by the artist Benjamin Levy and music composer Hannah Levy in New York City, where he graduated from the Bronx High School of Science. After graduating from Yale College (B.S., Molecular Biophysics and Biochemistry), Dr. Levy entered the Medical Scientist (MD/PhD) Training Program at New York University School of Medicine. There he earned his PhD under the mentorship of Drs. Peter Elsbach and Jerrold Weiss, characterizing neutrophil-derived antimicrobial proteins and peptides. Inspired by his wife Sharon’s example, he chose Pediatrics and completed both residency and fellowship at Boston Children’s Hospital. He is currently Professor at Harvard Medical School as well as principal investigator, staff physician in Infectious Diseases and the Director of the Precisions Vaccine Program in the Department of Pediatrics, Boston Children’s Hospital. The Precision Vaccines Program is an academic program that fosters international collaboration between academia, government, and industry for development of vaccine formulations optimized to protect vulnerable populations. Dr. Levy’s laboratory is focused on modeling vaccine-induced human immune responses in vitro using a variety of platforms including three-dimensional microphysiologic systems as well as global molecular (“OMIC”) approaches to accelerate and de-risk development of vaccines optimized for populations with distinct immune responses, including those at the extremes of age who suffer the most infections. He currently leads or co-leads multiple NIH/NIAID-supported studies, including (a) Adjuvant Discovery and Development Program contracts, leveraging high throughput screening to discover, characterize, and formulate novel small molecule adjuvants to enhance vaccine responses of vulnerable populations such as infants and older adults and (b) systems biology projects via the Human Immunology Project Consortium and the Immune Development in Early Life (IDEAL) program to define biomarkers of vaccine responsiveness, respiratory infection and asthma.

- 4:28How IoT Can Boost Renewable Energy? | Ahmed Ouesleti | TEDxSouthMediterraneanUniversityThe transition to renewable energy is essential for a sustainable future, but the variability of solar and wind power presents major challenges to grid stability and efficiency. The Internet of Things (IoT) offers a powerful solution by enabling real-time monitoring, automation, and optimization of energy systems. In this talk, Ahmed Ouesleti explores how IoT is transforming renewable energy, with a focus on applications in Tunisia and beyond. He will discuss how IoT-powered smart grids, predictive analytics, and automated microgrids can make clean energy more reliable, cost-effective, and accessible. Ahmed Ouesleti is a dynamic Business Development & Sales Manager with a strong track record in the automotive and renewable energy sectors. With expertise in sales strategy, market expansion, and strategic partnerships, he has played a key role in driving growth at Bako Motors and leading innovative projects in sustainable mobility. His experience spans business development, marketing, and customer experience, positioning him as a key player in scaling operations and delivering impactful solutions in emerging markets.
