Nicole D’Ascenzo,  Italian, Doctor of Physics. He used to work at the German Synchrotron Institute, the Russian Academy of Sciences, and the Russian State University of Atomic Research. As a member of the IEEE Photonics Society Committee, he has participated in many major IEEE international seminars. From 2015, he is working as a professor and doctoral supervisor in the College of Life Science and Technology of Huazhong University of Science and Technology. In addition, he is also the professor at Wuhan National Laboratory for Optoelectronics.

Professor Nicola D’Ascenzo has published more than 260 academic papers in international high-level journals such as Physics Review Letter, IEEE Electron Devices Letters, Physics Review D, Sensors, Applied Mathematics Letters, etc.  He has also written 4 monographs.

In 2005, Professor Nicola D’Ascenzo demonstrated the feasibility of applying silicon photomultipliers to PET, and designed a set of PET system based on the silicon photomultiplier, containing "Time of Flight (TOF)" and "Depth of Incidence (DOI)". This design method has become one of the templates of modern PET system design.

From 2006 to 2009, Professor Nicola D’Ascenzo proposed a modern hadron energy meter for separating the components of the high-energy jet generated by the collision of high-energy particles, which solved the key problem of the particle size of the hadron energy meter.Further more, he has built a high-granularity energy meter prototype based on silicon photomultiplier and successfully applied to the high-energy physics experiment of the European Organization for Nuclear Research (CERN), which verified the feasibility of the detector's application in high-energy physics experiments. Professor Nicola D’Ascenzo's design was adopted by the International Linear Collider (ILC) experimental group, and was included in the "Technical Design Report" as the blueprint for the International Linear Collider Energy Meter.

From 2013 to 2015, Professor Nicola D’Ascenzo obtained a more efficient and accurate way to simulate avalanche mechanisms and processes based on dynamic physics methods by fusing aerodynamics and magnetic fields in the same dynamics framework. It is the first time in the world to realize the overall improvement of precision, performance, physical meaning and computing cost in high-performance computing system. Professor Nicola D’Ascenzo’s paper in this research was recommended by Chetverushkin Boris Nikolaevich, who is one of the members of the Presidium of the Russian Academy of Sciences, and published in the top Russian scientific journal Russian Academy of Sciences Doklady Mathematics.

In 2015, Professor Nicola D 'Ascenzo was the first one to introduce 3D silicon crystal technology to the field of silicon photomultiplier, and proposed an innovative 3D structure digital silicon photomultiplier, using a new design method to raise the silicon photomultiplier to a new level. The design of the photodetector provides a brand-new design idea. The book  of this achievement,"The Digital Silicon Photomultiplier",was published in "Optoelectronics".

In 2016, Professor Nicola D’Ascenzo was awarded the honorary title of "Morice Region Ambassador" by the President of Italy for his outstanding contribution to the Sino-Italian international scientific and technological exchange. Invited to give an important academic report at the 29th IEEE Photonics Conference (IPC): "China Silicon Photomultiplier Technology", and an important academic report at the 4th International Conference on Photonics, Optics and Laser Technology (PHOTOPTICS): "Design and Test of SiPM Structures in CMOS Technol".

In 2017, the national international scientific and technological cooperation project "Joint Research and Development of All-Digital Silicon Photomultiplier Devices", which was participated by Professor Nicola D’Ascenzo, passed the acceptance successfully, and the evaluation results of all acceptance experts were "excellent". In this project, for the first time, 350 nm CMOS technology was used to develop SiPM. The device is optimized for the needs of positron emission tomography and is competitive with most custom commercial technologies available today.

In 2018, Professor Nicola D’Ascenzo led the team to use the self-developed silicon photomultiplier-based flat-panel digital PET for the first time to monitor the oxygen-15 produced by the proton beam reaching human tissues. This discovery means that the world problem of proton beam online monitoring is expected to be solved, thereby improving the effect of proton knife on tumor treatment and improving the cure rate and survival rate of patients. Related results were published in the international authoritative journal "Sensors".
