Dear Professor Mazzinghy,
It would be nice to give the talk to your students next Friday (15th July) at 9:30 am Brazil time.
Could you please send me the details of the logistics (online meeting, etc) to my email (lmartinez@randoanalytics.com).
I look forward to meet with you and your students during the talk.
Regards,
Dr. Luis M.
