Akhlesh Lakhtakia is Evan Pugh University Professor and Charles Godfrey Binder Professor of Engineering Science and Mechanics at the Pennsylvania State University. His research focuses on electromagnetic fields in complex materials, such as sculptured thin films, chiral materials and bianisotropy. His recent work on industrially scalable bioreplication, an emerging form of engineered biomimicry, has promise for harvesting of solar energy as well as for pest eradication. His technique for visualization of latent fingerprints was covered in a NOVA film in 2012.

Samuel Serna is one of the 2019 OSA Ambassadors. He is developing novel hybrid devices in silicon using photonic crystal waveguides and cavities and exploring methodologies to measure their nonlinear properties. Currently, he leads an international initiative between France (C2N) in Dr. Laurent Vivien’s group and the USA (MIT) in Prof. Juejun Hu’s group to develop chalcogenide hybrid waveguides for nonlinear integrated photonic applications . He was the President of the OSA-SPIE student chapter in 2010 at the National University of Colombia (Sede Medellin ). He was also the President of the Student Chapter of Optics – Paris, Palaiseau Cedex, France.

Hugo Fragnito received his B.Sc. from the Universidad de Buenos Aires (1976) and his PHD from Unicamp (1984). He was a guest researcher at the AT&T Bell Laboratories (Holmdel, 1987-1989). He was a Full Professor at Unicamp, director of the Center of Optics and Photonics Research (CePOF-Unicamp), Coordinator of the National Institute of Photonics Science and Technology (Fotonicom) and Coordinator of the KyaTera Project. He works with nonlinear optics, parametric devices, optical amplifiers, WDM systems, photonic crystal fibers and photon-phonon interactions in optical fibers. He is now a Full Professor at Mackenzie University, in São Paulo.

Ivan Aldaya received his bachelor in telecommunications engineeringfrom the Univesity of Navarra (2006) and his PHd in technonolgy and communications from the Monterrey Institute of Technology and Higher Education (2013). He is now an assistent professor at the State University of São Paulo. He works with optical communications and photonic devices. 

Rickson Mesquita is an Assistant Professor (MS3-1) at the University of Campinas (Unicamp) and a visiting Professor at the University of Pennsylvania (Penn).  He received his B.Sc. (Physics) from Unicamp in 2002, andhis Ph.D. from the same university in 2009, after spending one year as a visitor student at the Optics Division of the Massachusetts General Hospital (PMI Lab, David Boas, PI).  His Ph.D. thesis introduced the applications of diffuse optics to neuroscience in Brazil.  He joined the Gleb Wataghin Physics Institute (IFGW) of the University of Campinas in February 2011, following a two-year postdoctoral fellowship at UPenn (Biomedical Optics Lab, Arjun Yodh, PI). His current interests span fundamental and applied questions in optics, medical physics and biophysics.  Areas of ongoing research include: biomedical optics, light transport in diffusive media, optical properties of tissues, functional imaging and spectroscopy of living tissues, photodynamic therapy and cancer.  


Lázaro Padilha received his BSc. in Physics in 2001 and his PhD in 2006 from the Universidade Estadual de Campinas. The main topic of his thesis research was nonlinear optical processes in CdSe and CdTe quantum dots. After his PhD, he worked as post-doctoral researcher at CREOL – University of Central Florida, working on nonlinear optcial materials, and at the Los Alamos National Laboratory, ehre the research was focused on multiexciton interaction in semiconductor nanostructures. Currently, Padilha is an Assistant Professor at the Instituto de Física “Gleb Wataghin”, at the Universidade Estadual de Campinas. Understanding novel physical phenomena in quantum confined structures through advanced spectroscopy techniques, going from the fundamental studies to the device testing, is the main interest of the Ultrafast Spectroscopy Laboratory led by Prof. Padilha, within the Ultrafast Phenomena and Optical Communications Group – GFURCO.  The group main tool is based on ultrafast laser systems, with pulses down to 20 fs, which allows the monitoring of most of the recovery processes involved in electron dynamics.
