Dr. Oschwald studies a variety of conditions, primarily focusing on aggressive forms of cancer and the underlying genetic factors that influence treatment options. He has researched hereditary kidney cancers, identifying specific genetic mutations that lead to severe metabolic issues in patients. Additionally, he investigates how psychosocial stress affects pain perception, providing insights that could lead to better pain management strategies. His work also extends to innovative imaging techniques for monitoring explosive materials, benefiting both material scientists and safety engineers.
Key findings
In the study of metastatic kidney cancer, 3 young patients exhibited hyperlactatemia due to genetic mutations, which are crucial for accurate diagnosis and treatment.
Whole-exome sequencing revealed that 94% of tumors from 97 advanced cancer patients harbored mutations that could inform treatment, yet only 5% received therapy based on this genetic information.
In stress-induced analgesia research, acute stress increased heat pain tolerance without altering the threshold for pain onset, revealing insights into pain management.
A novel x-ray imaging system captured real-time thermal explosions in explosives, improving understanding of explosive behavior and contributing to safety advancements.
DNA analysis of 44 centenarians identified 130 disease-related genetic variants, highlighting that genetic predisposition alone does not dictate lifespan or health outcomes.

Plain English This study looked at how a specific type of explosive, called HMX, changes its structure during phase transitions, specifically from one form (γ) to another (δ). Researchers found that this change happens through a process where one form starts to grow from the other, even though the volume difference isn't large enough to typically affect melting points. They also explained that a thin layer of melted material at the interface helps this transition by lowering energy barriers, showing that this "virtual melting" idea can apply more broadly in material science.

Plain English This study examined a rare and aggressive type of hereditary kidney cancer in three young patients aged 19, 20, and 37. These patients showed extremely high levels of lactate in their blood, indicating severe metabolic issues, which were linked to specific genetic mutations in the cancer cells. The findings highlight the importance of identifying genetic changes to make accurate diagnoses, as these mutations play a critical role in the cancer's development.
Who this helps: This research benefits patients with rare kidney cancers and their doctors by improving diagnosis and treatment options.
Plain English Researchers studied how sudden stress affects people's ability to handle heat pain. They found that acute stress increased heat pain tolerance—meaning people could endure more pain—but did not change the point at which pain began. This increase in tolerance didn't seem to be connected to stress hormones or anxiety levels.
Who this helps: This helps patients dealing with pain and stress, as understanding this process can guide better treatment options.

Plain English This study looked at how whole-exome sequencing (WES) can help doctors make better treatment decisions for patients with advanced cancer. Researchers analyzed tumor samples from 97 patients and found that nearly all (94%) of them had mutations that could guide therapy, but only 5% of patients actually received treatment based on these findings. The results highlight the potential for WES to uncover important genetic information that could lead to better-targeted therapies for cancer patients.

Plain English This study looked at the DNA of 44 centenarians (people over 100 years old) from the Ashkenazi Jewish community to see if they carried known disease-related genetic changes. Researchers found 130 genetic variants linked to diseases that are rare in the general population, including those that can cause serious health issues like cancer and heart disease. Notably, even some centenarians with genetic risk factors for Alzheimer’s disease did not develop the illness, showing that having these variants does not necessarily mean a shorter life.
Who this helps: This research benefits patients and healthcare providers by providing insights into how genetics can influence longevity despite disease risks.

Plain English Researchers created a new x-ray imaging system that captures continuous images of events as they happen. They used this system to study thermal explosions in a specific explosive material and successfully observed these explosions in real-time. This technology is important because it can help scientists better understand how explosions occur, which can improve safety measures and the design of explosive materials.
