Dr. Tzortzakis’ expertise lies in the field of intense ultrashort laser pulse interaction with matter and he has a broad experience in the following domains:

- Nonlinear interactions of intense femtosecond laser pulses with matter

- Advanced shaping in space and time of light with applications in materials processing

- Nonlinear laser propagation phenomena - filamentation

- Integrated photonic circuits in the bulk of transparent solids

- Quantum and complexity physics with photonic lattices

- Intense tunable THz sources and THz nonlinear Optics

- Tunable THz metamaterials

- Environmental/atmospheric physics

His research team deals with both fundamental science aspects as well as technological applications. The polyvalent nature of their laser facilities allows studies in cross-disciplinary science including physics, chemistry, materials science and bio-medicine.

Dr. Tzortzakis has a long successful track record in organizing and participating in national and international research funding projects, summing ~$10M in the last 10 years. For more than 20 years, he has participated in European Union research funded projects (Greece, France), National research funded projects (Qatar-NPRP, France, Greece) and bi-national projects (Qatar-Greece, France-Germany, Greece-France), while he has been awarded many “Excellence grants” in Greece and the EU, including a Marie Curie Excellence Grant of 2M€.

He teaches on regular basis, classical mechanics, electricity-magnetism, quantum mechanics, optics and thermodynamics courses. He has supervised >40 undergraduate and graduate students (7 PhD). He is a recognized expert in nonlinear laser propagation phenomena and has created the website, a unique information resource for the related scientific community.

Dr. Tzortzakis has been chair/co-chair and member of scientific committees for many international conferences. He has more than 130 peer-reviewed papers in high impact international journals (~6000 citations, h-index=39) and has given more than 180 presentations and 90 invited/plenary talks at international conferences.
