Bio

Hello! I have earned a dual B.S. in Physics and Pharmaceutics at Zhejiang University in 2022, advised by Prof. Tingjun Hou, focusing on Computer-aided Drug Design After that I am involved in a Master program at Zhejiang University and got an internship in Carbon Silicon AI, a startup company, continuing my research in AI-aided Drug Design. In the future, I will go to UW Allen School for my Ph.D. study, advised by Prof. David Baker for ligand drug design. My CV could be found here.

My research interests are computer-aided drug design. Specifically, I am currently working on (1) structure-based drug design methodology (molecular generation and virtual screening approaches) (2) generative modeling (3) molecular dynamics. Basically, I’m also an AI4Science researcher.

山中何太冷,自古非今年。
沓嶂恒凝雪,幽林每吐烟。
草生芒种后,叶落立秋前。
此有沉迷客,窥窥不见天。
It's cold in the mountains, and not just this year.
The jagged cliffs are always piled high with snow, and the deep canyon species of trees are always spitting mist outward.
The grass is still sprouting in June, and the leaves start falling in August when they first arrive.
And here I was, mesmerized like a drug addict who had just finished a hit.

从明天起,做一个幸福的人
喂马,劈柴,周游世界
从明天起,关心粮食和蔬菜
我有一所房子,面朝大海,春暖花开
从明天起,和每一个亲人通信
告诉他们我的幸福
那幸福的闪电告诉我的
我将告诉每一个人
给每一条河每一座山取一个温暖的名字
陌生人,我也为你祝福
愿你有一个灿烂的前程
愿你有情人终成眷属
愿你在尘世获得幸福
我只愿面朝大海,春暖花开

Face to the sea,spring blossoms
From tomorrow,be a felicific man.
Feed a horse,split firewood,
and travel around the world.
From tomorrow,only care about cereal and vegerable.
I have a house facing to the sea.
There is spring all the year around and all is blooming.
From tomorrow,communciate with every kinsfolk.
Tell them my happiness.
What the felicific lightning has told me is
what I will tell everyone.
Give every river and every mountain a fragant name.
Stranger,I also bless you.
Hope you have boundless prospects.
Hope you have your Jack or Jill.
Hope you find your happiness in the world.
I only shall face to the sea and long for spring blossoms.

A conversation at the bottom of the heart
You have fulfilled your long-standing dream, and broken through all obstacles.
Why do you still feel so painful?

At the moment I realise my dream,
I really felt great satisfaction at the bottom of my heart.
But almost in an instant,
I felt the endless nothingness.
What did the aurora bring to me?
There seems to be nothing.
I still clearly remember the palpitation in my heart when I dreamed of seeing the aurora as a child,
but when I grew up, the throbbing became lighter and lighter.
I was overwhelmed by life, and was no longer able to complete the so-called dream.
But when I buried my dream,
my heart was unwilling.
So, I' ve tried my best,
and came here with the body that I didn't know how long I could live,
I long for the aurora to bring me an eternal meaning,
so that I can fight (against) life bravely.
But that doesn't exist.
It has no meaning at all.
My life will not change, and my story will not fly to the blue sky.
In that case, what is the meaning of life?
The dream that can be moved for it will be dull after it is realized.
All our pursues will turn into nothingness in the end.
Why should we purse it?
So, I'm not going to go on.
Since life has no meaning, let me go.
Let me go to the abyss, to embrace the eternal nothingness,
to embrace the eternal death.
