Short Curriculum Vitae

Prof. Pietro Patimisco is an Associate Professor at Physics Department of University of Bari. His main scientific skills are related to the development of spectroscopic techniques for studying the light-matter interaction in the infrared range. The main investigated areas are: i) µ-Raman and photoluminescence spectroscopy to study the thermal mapping of quantum devices, and ii) infrared molecular spectroscopy for sensitive and selective detection of molecules using quantum based sources.

Since 2017, he is the head of the technical committee of the joint-research lab PolySense, created by THORLABS GmbH and Technical University of Bari, devoted to the development and implementation of novel gas sensing techniques and the realization of highly sensitive photoacoustic trace-gas sensors.

In 2014, he has been a Visiting Researcher at Laser Science Group, Electrical and Computer Engineering Department, Rice University, Houston, Texas) for development of novel spectroscopic techniques for molecular infrared detection.

In 2018, he has been a Visiting Researcher at Institute of Laser Spectroscopy in Shanxi University, Taiyuan, China, within the “Hundred Talents” project of Chinese Academy of Science. In 2023, he was awarded funding for research through the “High Foreign Expert Introduction Program” with the project “Research on ultra-sensitive Photoacoustic and Photothermal Spectroscopy based on custom tuning forks”.

From 2022, he is the responsible of the work package activities within the “Dipartimento di Eccellenza 2023-2027 project” focused on “Lab on Chip and Breath Sensing” within the program “Cutting-edge Sensors for Health”. He is also responsible for the University of Bari research unit in the European Project “Passepartout – Photonic Sensors for Pollution Monitoring” and for the national project PRINN “Surface and Interface acoustic wave-driven Microfluidic devices BAsed on fs-laser technology for particle sorting”. From 2022, he is fully involved in PNNR National Research Centre for Agricultural Technologies (AGRITECH2022) and PNRR Extended Partnerships “National Quantum Science and Technology Institute” (NQSTI2022).

His research activity is documented by more than 240 Scopus publications and 3 filed patents (more than 7900 citations, h-index 54). He has given more than 60 presentations at international conferences and workshops, more than 10 as invited/keynote/plenary speaker. He is editor of Sensors (MPDI) and guest Editor of Photoacoustics (Elsevier). Since 2024 he is honorary professor at Jinan University in Guangzhou (China).

Pietro Patimisco is co-founder of “PolySenSe Innovations”, a spin-off company of the Polytechnic of Bari, devoted to the development of optical-based sensors, technical training for companies, and to find solution to strategic problems.

From 2019, he has been ranked among Top 2% Scientists in the world by Stanford University, USA. Scopus also ranks Pietro Patimisco among the top three authors worldwide in the topic “Photoacoustic Gas Detection Systems” (T.8274).
