About Me


I am an Assistant Professor at Arizona State University in the School of Earth and Space Exploration and the Beyond Center for Fundamental Concepts in Science.  

I am fascinated by all questions regarding the nature of life in the universe: How did life begin? How common is life? Are there universal laws of biological systems, as true here on Earth as they might be for extraterrestrial life should we ever find it? Its pretty exciting science, in part because there are currently more questions than answers!

Just wondering, I've been keeping an eye on and the information being relayed there. And I noticed over the last few months every time the Sun Emits Solar Winds towards earth and the Site predicts the dates of arrival. On various locations around the world the weather turns severe on those dates. It appears to happen when Solar Winds are somewhere above 350 km/s. Now the Coronal Holes of the Sun seem to have enlarged quite a bit in the last year or two, causing these Solar Winds to emit more powerfully. They do not appear to be decreasing anytime soon. Any Astrobiologists seeing this correlation between the Sun, its changes, the Holes, the winds, and our planet too? .. 

One last question, we have examined other Stars in the Universe go into Nova, and I'm sure the timelines of these events would appear to be random due to the immensity of the universe. And to see a Star Nova twice in a human lifetime would be most likely impossible. But has anyone at least tried? 

My last question, I also noticed the span between Solar Min and Max is usually around 11-13 years .. But between the last one and the current one it was only about 5 years. I didn't see such a short gap between cycles at least in the last few decades. Are there any? ..

I have a question!
I am interested in studying astrobiology at phd in the United States!
I've been a Masters in Atomic Physics!
my thesis is about the effect of cold atmospheric pressure plasma on cancer cells!
Which university can I apply?
Thank you.

Awesomeness!  It would be great to reach out to the wider astrobio community that way.

Hey Sara!  I'm curious to know if you're the organizer for the ASU astrobiology activities on SAGANet.  I'm considering trying to implement something similar for our Astrobiology Journal Club as well as a planned astrobiology lecture series here at CU in Boulder, so I'm looking for any advice on how to get that set up.  Thanks for any help you can offer!

I spoke with Hannah and with our schedules emailing looks like it will be the best way for us to communicate with only a few days till our lesson! We will email you today (I see her soon, in class!) Thanks!

Hello Sara! Wanting to see if you have any ideas for our discovery room lesson. Myself and Hannah are thinking about doing an activity with static electricity!

Thanks for opportunity, I enjoyed the discussion despite the technical problems we experienced.

Don't worry, when it comes to interdisciplinarity nobody knows where they are standing :)
