Professor in Faculty of Veterinary Medicine and Animal Science of University of São Paulo since 2011. Collaborated and concluded experiments with several species (Equine, Bovine, Swine, Ovine, among others) in the area of #8203;#8203;sperm quality assessment with the use of fluorescent probes (epifluorescence microscopy and flow cytometry) and computer-assisted semen analysis (CASA). It currently has its index h = 18 (Scopus) and has published more than 82 articles and more than 200 abstracts. In the five years (2016-2020), he participated in research projects with researchers from the Universidad de La Frontera (Chile) and the University of Girona (Spain). In 2018 he started partnerships with researchers from the University of Copenhagen (Denmark), North Caroline State University (USA), and Purdue University (USA). I have already completed the orientation of 3 Ph.D. students, 10 Masters, and 14 Scientific Initiations and offering opportunities for more than 210 students and professionals from different regions of the country in courses for Improvement, Dissemination, and Professional Practice (university extension courses). Currently, I advise one master's student and 2 Ph.D. students and co-supervises a Ph.D. student at the Universidad de La Frontera (Chile). I'm a reviewer of 12 international and 7 national scientific journals, being a member of the Editorial Board of Animal Reproduction Science (2020-2021). In 2019, I started a project with the University of Illinois (Urbana-Champaign) and acted as Visitor Research in the Laboratory of Dr. Robert V. Knox since December 2019 (FAPESP-2019 / 15668-3). As for administrative participation, I was served as Coordinator of the Post-Graduate Program in Animal Reproduction at FMVZ / USP (2016-2018). I'm currently Financial Director of the Veterinary Medicine Foundation (FUMVET). (Source: Lattes Curriculum)

The ideal method for artificial insemination (AI) would be the use of cryopreserved semen; however, it is not applied by the pig industry because similar results compared to refrigerated semen at 17°C have not been achieved in the pregnancy rate and the number of piglets per parturition. Nevertheless, cryopreservation is the most efficient method for long-term preservation of mammalian sp…
Despite the great scientific investments, boar semen cryopreservation stills an important challenge for science, regarding post-thawed boar semen quality, regardless pre-cryopreservation quality or cryopreservation protocol used. Some proteins have been described as freezeability biological marks of boar semen. However, seminal plasma have a wide range components, so it lead us to believe…
Boar spermatozoa arising from the sperm-rich ejaculate fraction are reported to have a more stable plasma membrane and are more resistant to cold shock and premature acrosome reaction than spermatozoa from the whole ejaculate. Furthermore, seminal plasma (SP) can increase the cryotolerance of boar spermatozoa, and in other domestic species, it has the ability to reverse cryopreservation d…

The use of metabolomics and the micro-RNA profile evaluation to study andrology and sperm function in boars is still very scarce. In recent projects completed by our group, we were pleasantly surprised to find that the type and sometimes the number of small molecules and micro-RNAs vary between ejaculates with good freezing capacity and ejaculates with low capacity to withstand the freezi…
The cryopreservation of swine semen holds great potential for growth in global artificial insemination. Some of the favorable aspects of this technique include semen preservation for extended periods and its transfer over long distances, which can contribute to the productive efficiency of intensive pig farming. However, a challenge faced in its utilization is the modulation of the intens…
Pig industry must always cherish the interactivity and globalization of its information, and the generated researches should reach the greatest number of farms as possible, so that knowledge is widely disseminated. Genetically superior semen diffusion is facilitated by the use of frozen semen. However, the freezing results obtained from the breeding centers are differents and demonstrate …
The present study intends to evaluate the effects of seasonal infertility on productive and reproductive performance in sows of Brazilian pig herds and what influences on productivity in commercial farms. The retrospective study will be conducted through the analysis of five year results (2015-2019) of commercial farms belonging to DB Genetics located in Minas Gerais, Brazil. To evaluate …

The aim of this work will be to evaluate how supplementing freezing media with reduced glutathione (GSH) or BHT affects in-vitro sperm fertility and its impact when a single insemination is performed at different intervals before ovulation. Experiment 1- In total 5 healthy boars from the Landrace x Largewhite, 2-3 years age will be used in this study. Ejaculates will be collected and pool…
The use of cryopreserved semen in modern swine production accounts for only 1% of all artificial inseminations performed worldwide, hence, its applicability is still very restricted, demanding more studies aiming at improving this biotechnology, which would lead to its full implementation into the commercial level. On this path, several techniques have been developed and applied in recent…
Despite great scientific investments, boar semen cryopreservation still presents an important challenge for science, regarding post-thawed boar semen quality, independently of pre-cryopreservation quality or cryopreservation protocol used. Some proteins have been described as freezability biological marks of boar semen. However, seminal plasma has a wide range of components, so it lead us…
