Laeticia Petit appointed as Assistant Professor at ORC

French-born Laeticia Petit joined TUT’s Optoelectronics Research Centre (ORC) at the beginning of August. Her areas of expertise include photonic glasses and glass-ceramics.

Despite Petit’s recent appointment, she has accumulated an extensive work and research history in Finland over the years. She has worked at nLIGHT Corp. in Lohja for several years, she is a long-time docent at Åbo Akademi University in Turku and she has also been an Adjunct Professor at TUT’s Department of Electronics and Communications Engineering since January.

By original education, Petit is a Doctor of Science from the University of Bordeaux I where she completed her doctoral degree in Solid-State Chemistry and Materials Science Engineering in 2002.

“In my research to date, I have examined the role of structure and property relationships in a wide range of active and passive oxide and non-oxide glasses. These have ranged from silica to chalcogenide glasses, from low to high non-linear refractive indexes. These glasses are mainly used in photonics and biomedical applications,” Petit lists.

WHO?

Laeticia Claudette Petit, born in 1975 in Tremblay, France

 

Degrees:

  • PhD in Solid-State Chemistry and Materials Science Engineering in 2002, Institute of Condensed Matter Chemistry of Bordeaux, University of Bordeaux I, France.
  • MSc in Physical Chemistry, in 1999, University of Paris VI, France.
  • BSc in Physical Chemistry in 1996, University of Paris VI, France.

 

Key positions and appointments:

  • Manager of Glass Research at nLIGHT Corp. in Lohja, Finland, 2012–2016
  • Senior Glass Scientist at nLIGHT Corp. in Lohja, Finland, 2009–2012
  • Research Assistant Professor at Clemson University in SC, USA, 2005–2009
  • Postdoctoral Research Fellow at College of Optics and Photonics, CREOL & FPCE at the University of Central Florida in FL, USA, 2002–2005
  • Docent at the Inorganic Chemistry Laboratory of Åbo Akademi University since 2013
  • Adjunct Professor at the ELT department of TUT since January 2016

 

Family: married to Jonathan Massera, who works as Assistant Professor in the ELT department. Son Joona (3).

Hobbies:

Petit likes to cook, hike in the forest and pick up mushrooms and berries. During winter time, she enjoys skiing and ice skating – “although I am only a beginner.” Her Finnish friends are always surprised when she tells them that she is learning ice-skating at the same time with her son. They tend to forget that in the Paris area, where she grew up, it is not usual to go ice-skating.

Laeticia Petit hopes that her research will lead to the development of next-generation photonic glasses that could be utilised not only in photonics but also in the fabrication of sensors for biomedical applications, for example.

“My work has included research on bulk, planar and fiber materials and devices for use as fiber lasers, chemical sensing and molded optics as well as applications utilising photo-induced property modification. In common terms, this means fabricating new glasses to be used as new fiber lasers or as new biosensors to track infection, for example,” Petit adds.

Laeticia Petit is a merited researcher in her field and she brings valuable expertise on glasses and glass-ceramics to TUT. In the past 15 years, she has published over a hundred papers in major international journals, merited two patents for novel tapered core fiber and microfluidic sensors and her papers have attracted over 1,200 citations, yielding an H-index of 20. She is also a reviewer for approximately two dozen major journals in materials science and engineering, glass chemistry and optics.

Petit has also served as a grant proposal reviewer for the US National Science Foundation since 2006 and for the National Science Center in Poland since 2014. Since 2013, she has been a member of the Technical Committee 20 (TC20, glasses for optoelectronics and photonics applications) in the International Commission on Glass (ICG) & American Ceramic Society. In addition to her own merits, she feels proud about the success of her students.

Petit joined TUT’s tenure track at the beginning of August and she has now worked at TUT’s Optoelectronics Research Centre for a month.

“To me, TUT seems to be a great place to work and grow. I am excited to work within the ORC and also with the University’s other departments,” Petit says.
