This color image shows a young man from the shoulders up smiling directly at the camera. He has dark, tightly curled hair and is wearing a dark, thin-framed pair of eyeglasses and a mustard-yellow T-shirt. The background is a soft-focus, shallow depth-of-field view of green leafy plants and foliage, with some architectural elements faintly visible, suggesting an outdoor garden or park setting during the daytime. The lighting is soft and natural. On the bottom-left corner of the image is text that says 2026 IPAC Visiting Graduate Student Research Fellow; in the bottom-right corner is an orange box with text that says "Alex Rodriguez University of Michigan Using weak lensing to detect cosmic filament IPAC Advisors: Andreas Faisst & Kyle Finner."
