Leonardo Schneider - Physicist, Biophysical scientist, Microfluidics engineer, and Programmer
About me
I am Junior Developer at Tarvos, where I develop front-end solutions for acquired datasets. I am physicist and obtained my MSc and PhD in Physics at Federal University of Paraná, Brazil. I worked for over 12 years in multidisciplinary groups side by side with engineers, biologists, chemists and physicians. I have over 10 years of experience in microscopy, photonics, biophysics, prototyping, and microfluidics engineering. Two years ago, I entered the programming world and started practicing Python, that raised even more my passion for programming and data analysis. Physics has been corroborating my critical and creative analytical thinking, which makes me an adaptive professional in several areas and groups.

Biophysical scientist
I have worked with groups of biochemist and physicians to improve the brazilian popular health system, implementing new diagnostics approaches and new methods for detection of sexual and tropical diseases. My experience in fluorescence techniques and single molecule spectroscopy allowed me to consult on a variety of research projects when I was member of FotoNanoBio Group in Brazil.
Physicist
Nothing gives me greater pleasure than working with different and new things, principally something that I must learn at its very first time, therefore this is a challenging work and we must keep in mind that the creativity is one of the best tool for doing it. I have done work in many branches of physics, such as computational quantum chemistry, polymeric surface superhydrophobicity, spectroscopy, microscopy and microfluidics.
Microfluidics engineer
I have developed microfluidic devices for diagnostic applications. I prototyped new designs for centrifugal devices and developed a new lateral flow device, as well as the reading machine that performs the clinical analysis of detection of numerous diseases obtained by the lateral flow device. I have extensive experience with CorelDRAW® software and rapid prototyping by CNC laser ablation micromachining.
Programmer & Developer
In my current job I am developing frontend and backend web services for agriculture applications. I addition to using HTML5, CSS, and JavaScript, I make use of Angular and NesJS. The dynamical interfaces collect data from plague traps on farms for better pest controlling and environmental caring. I also write scripts in Python3 and code in TypeScript. In my free time I use to learn and practice programming and I develop personal applications, that are in my GitHub.
Fluorescence Specialist
In my post-doc I worked with natural compounds, also with SUVs and GUVs, using UV-Vis, Absorption Spectroscopy, Fluorescence Lifetime Imaging (FLIM) and Fluorescence Correlation Spectroscopy (FCS) in studies of these materials. In FotoNanoBio Group I worked with Surface-enhanced Raman spectroscopy (SERS) to identify the mechanism of activity of some antibiotics on resistant bacteria. In the theoretical area I worked with modelling of electronic structures in atomic and molecular physics and semi-empirical and ab initio calculations, using programs such as Gaussian and GAMESS.
PROJECTS
Studied of Photophysical Properties of Flavonoids Extracted from Syngonanthus nitens, the Golden Grass | 2016 – 2018
USP, Ribeirão Preto, São Paulo – Brazil
During my PhD, I contributed to investigate natural extracts and search possible applications. My main role was the complete characterization of the extract of Golden Grass flavonoids and learn advanced fluorescence techniques. I ended up discovering that golden grass has incredible antioxidant potential and can be used in the pharmaceutical industry.

Diagnostic System Development | 2013 – 2015
IBMP, Curitiba, Paraná – Brazil
In collaboration of IBMP and UFPR, we developed a novel diagnostic system for point-of-care testing, or laboratory use, or performed in point-of-need. We created a new design concept, we refined the internal structures, and we designed the overall electronics of the equipment. From this project, it resulted a software copyright and a patent that was entirely written by myself.

Microfluidic Chip Development | 2010 – 2013
IBMP, Curitiba, Paraná – Brazil
I completely characterized the laser ablation equipment that produced the microfluidic chips. Furthermore, I designed, produced, and tested the microfluidic chips. The turning point was the optimised geometry stopvalves calculation using MatLab. I discovered the exact chip rotation that was capable to produce the ideal pressure to fill all the microfluidic channels before the same-time flow purging. Moreover, I supervised interdisciplinary research groups at large meetings and performed laboratory measurements.

Oil-water separation using superhydrophobic surfaces | 2007 – 2008
UFPR, Curitiba, Paraná – Brazil
Throughout my graduate work, I worked on the development and characterization of superhydrophobic surfaces for oil-water separation. In this project we could measure an incredible contact angle of 179° over the Polytetrafluoroethylene cured coating due the use of electrospray/electrospinning technique.
