I am pleased to share that I have been selected for the 2025-26 Fulbright Presidential STEM initiative award. This initrive was created by presidents Joe Biden and Suk Yeol Yoon to celebrate the 70 year alliance between our countries. I am excited to study the Dolomedes spiders of South Korea! 🇰🇷🕷️

I’m not ready for field season, but I miss my study species dearly. Enjoy these fishing spiders in copula. Males always expire shortly after insemination while still inside the female. Females cannibalize shortly after. Here, a male hangs from a female’s reproductive opening as she sits on my arm.

I was having a bad day, so my friend offered to take me to the field for an hour and collect pond water. I feel better now.

(Btw I don’t know anything about freshwater ecology so somebody tell me what I’m seeing bc it looks amazing)

I kept telling my friend how sad I was that I missed Lunar New Year in the States and couldn’t celebrate while in Germany. I returned to work this week and she surprised me with 약과 and 다식! I feel so loved. Happy year of the snake! ❤️🐍

Eight legs to bring a little joy to your timeline (skyline?). Zoropsis spinimana, aka the “Nosferatu spider.” Isn’t she so cute? 🥹

Thank you to @wolffspider.bsky.social and your lab @evoimec.bsky.social for a warm welcome in Greifswald! Please follow them and their amazing work!

2/ I had a physical copy of the magazine sent to my birth family. I cried when I saw this message from my father (Please be kind, he is learning English and I am learning Korean ^^;)
My father sent me an image of the dialogue box to show he received the magazine. He sends a message below saying “I’m proud you” - “I’m proud of you.” I respond “고마워요 아빠“ - Thank you dad I am happy you received the magazine.

🧵 1/ Words cannot describe publishing my first article in Korea as an adoptee. I am coauthoring a series on arachnid behavior in Donga Science (과학동아). It is surreal to see my Korean name in print.

Korea, I am still here and I am still your daughter.

A dialogue box showing a conversation between my colleague and I discussing how we got into spiders. Korean text: 한글 Dialogue "거미 연구자들이 거미와 사랑에 빠진 순간" 이항: 어떻게 처음 거미를 좋아하게 됐어? 정화: 어릴 땐 거미를 무서워했어. 어쩌다가 학부 때 곤충 박물관에서 거미를 관리하는 일을 맡아서 관심이 생겼지. 그러다가 2018년에 마다가스카르에 여행을 갔는데, 거기서 'Darwin's bark spider(다원의 나무껍질거미)'라는 세계에서 가장 큰 거미줄을 만드는 거미를 보게 됐어. 거미줄이 얼마나 멋지던지! 이항: 너도 취향이 참.... English Translation: Dialogue “The moment spider researchers fell in love with spiders.” Yihang: How did you first like spiders? Jeong-hwa: I was afraid of spiders when I was young. I got interested in taking care of them at an insect museum when I was an undergraduate. Then, in 2018, I went on a trip to Madagascar, where I saw Darwin's Bark Spider, a spider that makes the world's largest web. How wonderful the web is! Yihang: You have very interesting taste.

I found a horseshoe crab ornament and wanted to share it with my friends but I had a crisis trying to figure out what discord channel to put it in.

Dolomedes tenebrosus! My dissertation species. 🥰 This is a female (larger spider on left) and female (smaller spider underneath) mating. Males always die inside females after insemination and females will always cannibalize the males after mating.

🧪 What happens when an arachnologist and chemist try to communicate.

(I asked my friend how I could freeze spiders in copula using liquid nitrogen)
Me asking if I understood the assignment by drawing out how I understood my friends instructions: 1. LN2 stored in a big container 2. Pour LN2 from big container into soda bottle 3. Use gloves to pick up bottle 4. Use soda bottle to pour LN2 over spiders (using gloves!!!) My friend trying to explain the Liedenfrost effect to me by drawing LN2 hitting "spider skin." She notes that spider skin will be "hot" compared to LN2 and that has from the LN2 boiling off traps air. My friend asking if I could use a loose screen to get the spiders to copulate and actively dunk them into a vat of LN2.
