College Personal Statement — page 1

The

summer

I

turned

sixteen

,

I

built

a

machine

to

talk

to

asphalt

.

Not

literally

—

but

close

enough

.

Using

six

Arduino

sensors

,

a

secondhand

GPS

module

,

and

a

milk

crate

I

’

d

padded

with

bubble

wrap

,

I

spent

July

riding

my

bike

through

Southeast

Portland

recording

surface

temperatures

.

On

the

day

the

mercury

hit

107

degrees

,

the

parking

lot

behind

the

Lents

Boys

&

Girls

Club

registered

142.

Three

blocks

east

,

under

the

cottonwood

canopy

of

Kelly

Butte

Natural

Area

,

the

ground

held

steady

at

84.

That

fifty

-

eight

-

degree

difference

,

measured

by

a

jerry

-

rigged

thermometer

in

a

milk

crate

,

became

the

moment

I

understood

that

cities

are

physical

equations

—

and

that

I

want

to

spend

my

life

solving

for

equity

in

the

built

environment

.

I

didn

’

t

start

with

engineering

.

I

started

with

a

dunk

tank

.

For

three

years

I

volunteered

at

the

Lents

community

center

,

running

the

summer

carnival

’

s

most

popular

attraction

.

Between

shifts

,

I

noticed

that

the

kids

who

stayed

longest

weren

’

t

playing

—

they

were

hiding

in

the

shade

of

the

snack

tent

,

too

exhausted

by

the

heat

to

move

.

When

I

looked

up

Portland

’

s

heat

-

island

data

,

I

found

a

blank

spot

.

The

city

’

s

climate

office

had

coverage

downtown

and

in

the

West

Hills

,

but

our

neighborhood

,

where

median

income

is

forty

percent

lower

and

tree

canopy

sits

at

eleven

percent

,

was

an

inference

based

on

aerial

averages

.

So

I

decided

to

measure

it

myself

.

I

had

eighty

-

three

dollars

saved

from

babysitting

.

I

spent

forty

-

seven

on

a

starter

kit

,

nineteen

on

waterproof

casings

I

made

from

takeout

containers

,

and

the

rest

on

zip

ties

and

reflective

tape

.

I

watched

YouTube

tutorials

at

half

speed

.

I

fried

one

sensor

by

reversing

polarity

.

I

learned

that

GPS

signals

bounce

off

corrugated

metal

.

By

August

,

I

had

fourteen

thousand

data

points

and

a

heat

map

that

made

our

city

councilor

’

s

jaw

drop

at

the

September

town

hall

. “

This

is

better

resolution

than

we

have

in

the

Pearl

District

,”

he

said

.

He

wasn

’

t

exaggerating

;

I

had

better

resolution

because

I

cared

enough

to

pedal

slowly

.

The

project

taught

me

that

engineering

is

not

the

opposite

of

community

work

.

It

is

community

work

made

durable

.

I

watched

neighbors

translate

my

color

-

coded

map

into

Spanish

and

Vietnamese

so

their

elders

could

understand

why

the

bus

stop

needed

a

shade

shelter

.

I

saw

how

data

,

when

it

belongs

to

the

people

it

describes

,

becomes

advocacy

.

And

I

realized

that

the

kind

of

environmental

justice

I

care

about

doesn

’

t

happen

in

courtrooms

alone

—

it

happens

in

material

choices

,

in

stormwater

management

,

in

the

albedo

of

pavement

surfaces

.

I

want

to

study

environmental

engineering

with

a

focus

on

urban

heat

and

hydrology

.

I

am

drawn

to

research

on

permeable

pavement

systems

in

low

-

canopy

neighborhoods

,

and

I

hope

to

contribute

to

community

-

based

participatory

research

labs

.

More

broadly

,

I

want

to

learn

the

mathematics

and

thermodynamics

that

turn

observation

into

scalable

infrastructure

.

My

milk

-

crate

sensor

network

worked

because

it

was

cheap

,

local

,

and

specific

.

I

want

to

learn

how

to

make

solutions

that

are

all

three

—

but

built

to

last

twenty

years

,

not

twenty

days

.

My

grandfather

was

a

civil

engineer

in

Taipei

who

designed

bridges

.

He

used

to

say

that

every

structure

carries

two

loads

:

the

weight

of

what

it

holds

,

and

the

weight

of

who

it

excludes

.

I

think

about

that

constantly

.

The

heat

that

radiates

from

unshaded

asphalt

is

a

load

.

The

asthma

rates

near

the

I

-205

corridor

are

a

load

.

And

the

silence

where

data

should

be

—

that

’

s

a

load

too

.

I

want

to

build

systems

that

bear

all

of

them

differently

.

I

don

’

t

yet

know

exactly

how

.

But

I

know

where

to

start

:

with

a

sensor

,

a

question

,

and

a

willingness

to

ride

every

block

.
