London, UK, 11 Dec 2025, ZEX PR WIRE, Stelios Tzellos, Ph.D., continues to be recognized within the pharmaceutical industry for his contributions to oncology market analysis and strategic forecasting. With a formal background in molecular biology and biochemistry from Imperial College London and multiple years of applied experience in healthcare analytics, Tzellos’ work has informed commercial planning and strategic evaluation across multiple therapeutic areas, particularly within oncology.

Dr. Tzellos earned his Bachelor’s and Master’s degrees in Biochemistry and went on to complete a Ph.D. in Molecular Biology, all from Imperial College London. His doctoral research focused on Epstein-Barr virus (EBV) gene regulation, specifically the functional differences between EBNA-2 type 1 and type 2 proteins. His findings, published in peer-reviewed journals, helped expand understanding of how EBV regulates the expression of cellular genes like CXCR7 and viral genes such as LMP-1.

His academic contributions during his Ph.D. program include co-authorship of studies examining how specific amino acid changes in EBNA-2 affect the regulation of growth-promoting genes. One study, published in the Journal of General Virology in 2014, was titled “EBV EBNA-2 type 1 and type 2 proteins induce expression of the cellular CXCR7 and EBI2 genes through a mechanism involving a common motif in their transactivation domains.” Another article, where he was the first author, expanded on the same theme of differential gene activation.

In 2014, while working as an Oncology and Haematology Analyst for GlobalData, Dr. Tzellos was quoted in a widely circulated industry report forecasting trends in Hodgkin’s lymphoma treatment. That report examined the expanding use of Adcetris and the emergence of premium-priced therapies targeting relapsed or refractory (R/R) populations. In the report, Dr. Tzellos stated:

“Adcetris currently accounts for 77.6% of the total market and is predicted to make up 82.4% of sales by the end of the forecast period. Premium-priced pipeline therapies that target the R/R Hodgkin’s lymphoma population will find it easier to penetrate the market, as Adcetris has already opened the door for expensive therapeutics in this setting.”

The analysis helped contextualize the broader adoption of targeted agents and immunotherapies in hematologic malignancies and emphasized the commercial implications of label expansions and earlier-line use. Dr. Tzellos’ quote has since been referenced by healthcare publications analyzing pricing strategy and market evolution in oncology.

After his tenure at GlobalData, Dr. Tzellos joined IQVIA, where he continued to work in pharmaceutical analytics. He later moved into a commercial-facing analytics position at AstraZeneca in the UK. Across these roles, his focus has remained in strategic insight, analytics, and pharmaceutical development, particularly in oncology.

Dr. Tzellos’ professional experience intersects research, forecasting, and healthcare consulting. His work contributes to decision-making processes related to product planning, commercialization strategy, and global market evaluation. While he has not authored publicly available white papers under AstraZeneca or IQVIA, he continues to post periodically on Medium and LinkedIn about trends in pharmaceutical strategy and oncology analytics.

He resides in the United Kingdom with his wife and their two children. Outside of work, he has a range of personal interests including football, basketball, Formula 1, attending live music events, and engaging in DIY home projects.

Dr. Tzellos’ career exemplifies a transition from academic molecular biology research to high-impact pharmaceutical strategy and analytics. His ongoing work remains grounded in scientific evidence while addressing real-world commercial challenges in oncology drug development.

• Experience the Southern Serengeti with exclusive access to 2026’s calving season with Nakuja Expeditions, offering travelers unparalleled wildlife encounters, expert guidance, and unforgettable safari moments.

Arusha, Tanzania, 10 Dec 2025. ZEX PR WIRE, Nakuja Expeditions is proud to announce the availability of its 2026 Calving Season safari packages, offering travelers a unique opportunity to witness one of nature’s most dramatic wildlife spectacles. Scheduled from January through March, the Southern Serengeti becomes a dynamic nursery where thousands of wildebeest give birth, creating a vivid scene of life and survival that captivates wildlife enthusiasts, photographers, and adventure seekers alike. This experience centers not only on the Southern Serengeti plains but also the iconic Ndutu region, the heart of the calving season.

The Serengeti calving season is a spectacle of life, survival, and raw nature at its finest. Nakuja Expeditions guides travelers through this extraordinary event, ensuring each moment is experienced safely, responsibly, and with lasting memories.

The calving period is recognized as one of the most intense and fascinating events in Africa’s ecological calendar. Visitors will experience firsthand the synchronized births of young wildebeest against the backdrop of rolling plains, accompanied by the intricate interplay of predators. Lions, cheetahs, and hyenas take advantage of this period, making every moment an opportunity for high-drama wildlife observation. Ndutu, located within the Ngorongoro Conservation Area, becomes the primary gathering point for wildebeest mothers, offering unmatched visibility and concentrated wildlife action. Nakuja Expeditions’ expert guides provide crucial insights into animal behavior, ensuring that travelers can safely witness interactions that would otherwise be difficult to access.

“Our Calving Season safaris give our clients a privileged perspective on one of Africa’s most remarkable natural events. Front-row access is all about understanding, safety, and being in the right place at the right time,” said a spokesperson for Nakuja Expeditions. The company’s experienced team meticulously plans each trip, selecting lodges and camps in strategic locations across Ndutu and the Southern Serengeti to maximize visibility and comfort while minimizing disruption to the animals.

In addition to observing births, guests are treated to a diverse range of experiences that highlight the Serengeti’s extraordinary ecosystem. From guided game drives to expert commentary on predator-prey dynamics, travelers gain an immersive understanding of the annual rhythms that define the region. Photographers benefit from unparalleled opportunities to capture the dramatic, fleeting moments that characterize the calving season. At the same time, casual travelers enjoy the awe-inspiring spectacle of life unfolding in its raw form. The safari packages also include evening sessions to observe nocturnal activity, where predatory behavior and wildlife interactions create unforgettable moments of tension and excitement. Ndutu’s open woodlands and grass plains offer ideal terrain for both daytime and nighttime observation, making it one of the most photogenic locations during calving season.

Nakuja Expeditions emphasizes that early booking is essential, as availability is limited and demand for these specialized safaris remains high. The company’s expertise ensures that clients not only witness the spectacle safely but also gain a deeper appreciation for the ecological significance of the calving season. By combining local knowledge, logistical precision, and personalized service, Nakuja Expeditions delivers a safari experience that transforms wildlife observation into a once-in-a-lifetime adventure.

Travelers seeking a remarkable and immersive wildlife encounter for 2026 can secure their place on these exclusive Calving Season safaris, with a guarantee that Nakuja Expeditions will provide front-row access to the Southern Serengeti’s most extraordinary event, particularly the world-famous Ndutu calving grounds, delivering a journey that promises both awe and education at every turn.
