 Dr. Isidoro Gutierrez-Alvarez | Hematological Disorders | Best Researcher Award

Dr at Isidoro Gutierrez-Alvarez University of Huelva Spain

I began my research career with an internship at the Atmospheric Sounding Station (ESAt) in El Arenosillo, Mazagón (Huelva), part of the National Institute of Aerospace Technology (INTA). During this stay, I applied my programming knowledge to extract meteorological information from NASA’s MERRA-2 model and became familiar with the “Weather Research and Forecasting” (WRF) atmospheric simulation model, widely used for high-resolution atmospheric simulations. This contact with INTA has been maintained throughout my research career, conducting joint studies between the University of Huelva and INTA. 🌦️🌐

Later, I expanded these capabilities with the use of Lagrangian atmospheric dispersion models such as HYSPLIT and FLEXPART, which I used to study in detail the behavior of radon around the city of Huelva. Thanks to these models, we were able to simulate the transport behavior of radon from the phosphogypsum ponds to the city of Huelva, identifying that breeze events allowed the recirculation of air masses and their gradual enrichment in radon. These studies were published in two research articles in first-quartile journals. 🌬️🔍

During my Ph.D., I not only studied atmospheric radon but also the radon exhalation rates from the phosphogypsum repository. During this stage, I designed and built two reference soils for measuring exhalation rates, which are used to calibrate and verify the correct functioning of radon measuring equipment, especially those focused on radon exhalation. These reference soils demonstrated that it is necessary to insert the accumulation chamber a few centimeters when measuring exhalations to avoid significant leaks through the exhalation material itself. This research resulted in two articles, one of which was published in a first-decile journal. 🌱📊

Additionally, due to my knowledge of data analysis and programming, I have closely collaborated on other projects carried out by the FRYMA research group. Notably, I actively participated in obtaining and analyzing results in the works of Dr. Guerrero Márquez. 🤝💻

So far, I have supervised three undergraduate theses (TFG) and two master’s theses (TFM), and another two are expected to be defended in September 2023, totaling seven TFG/TFM. Moreover, I am co-director of a doctoral thesis titled “Development and improvement of techniques to characterize the properties of 222Rn in materials and construction systems; modeling the behavior of 222Rn inside homes,” where I play a major role in the academic supervision due to my familiarity with the subject. 📜🏠

Mr. ‌ Shunsuke Suzuki| | Thermodynamics | Best Researcher Award

Mr at Shonan Kamakura General Hospital,  Japan

 I am an accomplished researcher and academic, currently pursuing a Ph.D. at the Graduate School of Engineering, Kyoto University. With a strong background in radiation therapy and dosimetry, my research has focused on radiation-induced secondary carcinogenesis and the development of precise γ-ray dosimetry methods for boron neutron capture therapy (BNCT). I have published several papers and presented at numerous conferences, contributing to advancements in proton therapy and BNCT. Currently, I am introducing the “nuBeam” accelerator-based BNCT system at Shonan Kamakura General Hospital and continue to innovate in the field of radiation dosimetry and cancer treatment technologies.

Profile

 

Education, Experience, and Academic Achievements 🎓

I conducted research on radiation-induced secondary carcinogenesis during my master’s course at the Graduate School of Medicine, Hokkaido University, and presented my findings at an academic conference. Following my master’s, I joined the Minami-Tohoku Cancer Proton Therapy Center, where I published a paper on radiation-induced secondary carcinogenesis in children due to different proton therapy irradiation methods. Currently, I work at Shonan Kamakura General Hospital, where I am introducing the accelerator-based boron neutron capture therapy system “nuBeam” and presenting research on its initial evaluation at conferences and in scholarly papers. Additionally, I am conducting research on developing γ-ray dosimetry in neutron fields, which has been published and will be presented at an international conference. I am also pursuing a doctoral degree at the Graduate School of Engineering, Kyoto University, and will graduate this year.

Contributions to Research & Development, Innovations, and Extension Activities 🧪

In the realm of boron neutron capture therapy (BNCT), the radiation emitted by the BNCT machine is directly linked to the patient dose. Therefore, accurately evaluating the gamma ray dose through measurement is crucial for introducing BNCT into clinical practice. Measurement methods for gamma ray doses in BNCT fields currently vary among facilities, necessitating a universally applicable and accurate method. In Japan, a custom-built thermoluminescent dosimeter (TLD) (Panasonic, UD-170LS) with beryllium oxide powder in a quartz glass tube is used for 𝛾 dose measurement, but it is no longer manufactured or commercially available. Consequently, I investigated a method combining a commercially available Mg2SiO4:Tb TLD (TOREC, TLD-MSO-S) with a 6LiF sintered capsule, verifying its efficacy for 𝛾 dose measurement in an accelerator-based (AB)-BNCT system.
