Osnat Penn facts for kids

Osnat Penn (Hebrew: אסנת פן; born in 1981) is a smart Israeli scientist. She uses computers to study biology, focusing on how living things change over time (evolution), how cells work, and how our bodies fight off sickness (immunoinformatics). In 2013, she won a special award called the UNESCO-L’Oréal fellowship. She was the third Israeli woman in three years to get this award! She won it for her important work on the genetic reasons behind autism. Dr. Penn has been working at the University of Washington in Seattle since 2012, doing advanced research after getting her PhD.

Osnat Penn's Education and Early Work

Osnat Penn studied at Tel Aviv University in Israel. She earned three different degrees there! First, she got a Bachelor of Science degree in both Biology and Computer Science, focusing on a field called bioinformatics. Bioinformatics is like using computers to understand biological information, like DNA.

After that, she earned a Master's degree in Molecular biology. This field looks at how tiny parts inside cells work. Then, she completed her PhD in Computational Biology. Both her Master's and PhD were in the department of cell research and immunology. Her PhD project was about using computer methods to study how the HIV virus changes over time. Her professor, Tal Pupko, helped guide her research.

Before moving to Seattle, Dr. Penn also helped teach students at Tel-Aviv University. She was a teaching assistant for a class called "Introduction to Bioinformatics" from 2006 to 2009. She also taught other courses about bioinformatics and analyzing biological information from 2007 to 2011.

What Computer Programs Did Osnat Penn Develop?

Dr. Penn has created several helpful computer programs at Tel Aviv University to assist in biological research. These programs make it easier for scientists to study living things.

• GUIDANCE: This is a special tool on the internet (a web server) that helps scientists check how reliable their genetic sequence alignments are. It's like making sure puzzle pieces fit together correctly.
• RASER: This program, whose full name is the RAte Shift EstimatoR, helps scientists find out if the speed of evolution has changed in specific parts of a gene or in certain groups of living things.
• Pepitope Server: This tool helps map out tiny parts of proteins called epitopes. Epitopes are important because they are what our immune system recognizes when it fights off germs.

How Did Osnat Penn's Research Help Understand Autism?

Dr. Penn's research on the genetic causes of autism earned her the UNESCO-L’Oréal award and a grant of $40,000. This money helped her continue her important studies.

Her work focused on finding small differences in the genes of children with autism compared to their parents who do not have autism. This research helped scientists understand how complex the genetics of autism can be, especially when autism appears in a family for the first time (called sporadic autism).

Her discoveries could lead to new ways to check for autism before a baby is born (prenatal screening) or to diagnose it very early in life. It might also help develop new treatments, like gene therapy, which could help correct genetic issues.

Publications

Dr. Penn's research has been published in many important science journals. These include Cell, Genome Research, Molecular Biology and Evolution, Nucleic Acids Research, Systematic Biology, BMC Evolutionary Biology, PLoS Computational Biology, Bioinformatics, Proteins, Genome Medicine, Nature, Frontiers in Molecular Biosciences, Nature Ecology and Evolution, Genome Biology, American Journal of Human Genetics and Protein Engineering, Design and Selection.
